So under different conditions it will act.

3. Explain the factors on which the velocity of sound depends?

Velocity of sound depends on velocity and density of the medium on which it travels. It varies directly as the square root of elasticity and inversely as the square root of the density.

4. Do you know what is dyne?

Dyne is a unit of force or also referred as C-G-S (centimetre – gram –-second). It means that when a force is applied to mass of 1 gram, it gives acceleration of 1 centimetre per second.

5. Do you know what is “Convection”?

Convection is the process of transferring heat by movement of heated fluid such as water or air. In this process, the heated fluid expands, and gravity pulls the denser masses under them thus forcing them into motion. One good example is a draft of lamps and stoves.

6. Tell me what is dark matter?

Dark matter is an invisible matter in the space that can hold the stars into the galaxy. They have no effect of electromagnetic force on it, which means it does absorb, reflect or emit light that makes them practically invisible.

7. Tell me what is Quantum tunnelling?

Quantum tunnelling is the process where the particle passes through an obstruction or barrier to reach at another end. It is referred as tunnelling as the particle as “dug” out the way through the potential barrier.

8. A motor vehicle is moving in a circle with a uniform speed. Where will be the net acceleration of the vehicle?

towards the centre of circle

9. Tell me do you have any specific advice for dealing with panel interviews?

When you are being interviewed by a panel or a committee, it is vital to look at everyone as you answer each question. If Dr. X asks you something, state Dr. X's name in your reply but address it to all the people in front of you, not just Dr. X. Everyone on the panel is evaluating you and they each need to know that you recognize their presence and authority even if they don't ask you a question. You should also offer extra copies of your résumé/CV and publications list as you begin the interview. Smile and maintain eye contact. Finally, request contact information for everyone on the panel so you can write each of them an individualized thank-you note.

21. Explain what specific advice do you have for international students?

For international students looking for a job in a country where they don't have the correct work visa yet, it is important to clearly demonstrate that you and your set of experiences, expertise, skills, networks of contacts, pedigree, and credentials will provide the company a competitive advantage. Give them examples of what you have achieved that is unique to you and connect the dots for them by then explaining how this experience will benefit them-that you'll be able to solve problems more efficiently, more quickly, in novel directions, and so on. Why? If the company wants you-which they will determine and finalize in the actual interview-they will do what they need to do to get you, before the competition gets you. So look for opportunities in the interview to share exactly what achievements you have had that demonstrate your unique skill set. And remember: A company might have to go to the trouble of obtaining a work visa for you, but if they like you and see your value, they will do what is necessary to get you the job.

30. Tell me at what point in the interview process should a disability be discussed, if ever?

For the most part, I don't think you need to bring up a disability at all. In general, it is none of their business if it doesn't impact your ability to deliver excellence in the job. However, let's say your disability will affect your ability to take on certain tasks of the position. For example, say you have to be able to lift 25 pounds in order to operate a telescope or some other instrument, and your disability precludes you from doing that. In this instance, you can indicate the issue, and how you would work around it so as not to impact your ultimate productivity.

35. Explain at the end of the interview when they ask "do you have any questions for us?", what should I ask?

Yes, you wait for them to provide you with an offer before you start negotiating. If they ask during the interview about your salary expectations, you can say, "I am just focused on the position and organization right now and want to ensure that I am are right fit for the job." If they insist, you can ask them what their budget or budget range is. If they really insist, be ready with a range that you have researched in advance. The general rule is that the first party to mention money sets the limits. If you mention a number before they do and it is lower than what they had budgeted, you just did them a huge favor by saving them money.

36. Do you know what is Parallax and Distance Measurement?

To measure the distance to nearby stars, astronomers use an effect called Parallax. Parallax is the apparent displacement of an object because of a change in observer's point of view, for instance, when we look at object with one eye shut and then doing the same with other eye, there is a difference in the position of the object this is known as Parallax.

To measure the star position astronomer uses this technique. Once the star position is located after six month they will again calculate the apparent change in position.

41. Tell me which is responsible for the working of Newton's colour disc experiment?

Persistence of vision

42. Tell me what is the best way to introduce myself for an industry job, especially an entry-level position?

The answer depends on where you are in the hiring process. I will address this question from two points of view. On the one hand, let's assume that you are trying to get an interview and you are either applying for a job after seeing an ad or you are speaking with someone at the company with the hope that they will invite you for a formal interview. The key here is to share in the initial email what it is you can do for the other party and their organization by exemplifying problems you have solved, detailing the results of your solutions, and concluding how your experience uniquely prepares you to add value to their team. For an entry-level job, you are not expected to have tons of experience in a company setting. That said, the experiences you have had as a student are valuable and can be articulated in such a way as to demonstrate your ability to add value to their organization quickly.

43. Explain should I send a thank-you note by email or standard mail?

It depends on the sector. In general, it is always preferable to send a hand-written note by post because the extra mile you put in to express gratitude can give you a competitive advantage in the job decision process. Most people do not send any formal thank-you notes after interviews, so you should always do so. However, I recognize that certain sectors, such as government agencies, labs, and even some academic institutions are difficult to send mail to. In fact, I have mailed cards to professionals in the federal government only to have them get lost in a labyrinthine system of security. So if you think this might be the case with your prospective position, send an email thank-you note. And be sure to send one individually to each person who interviewed you, as opposed to a batch email to a group.

44. Do you know what is Quantum Physics?

The understanding of behavior of matter and energy at the molecular, nuclear, atomic and even microscopic levels is referred as Quantum physics

47. Explain what are the main job duties and responsibilities of physics teacher employee?

Physics teacher responsibilities are to compile, administer, and grade examinations, or assign this work to others; evaluate and grade students' class work, laboratory work, assignments, and papers; initiate, facilitate, and moderate classroom discussions; keep abreast of developments in the field by reading current literature, talking with colleagues, and participating in professional conferences; prepare course materials such as syllabi, homework assignments, and handouts; select and obtain materials and supplies such as textbooks and laboratory equipment.

Collaborate with colleagues to address teaching and research issues; serve on academic or administrative committees that deal with institutional policies, departmental matters, and academic issues; advise students on academic and vocational curricula and on career issues; prepare and deliver lectures to undergraduate or graduate students on topics such as quantum mechanics, particle physics, and optics; write grant proposals to procure external research funding; conduct research in a particular field of knowledge and publish findings in professional journals, books, or electronic media; maintain student attendance records, grades, and other required records; maintain regularly scheduled office hours to advise and assist students; plan, evaluate, and revise curricula, course content, and course materials and methods of instruction; participate in campus and community events; supervise undergraduate or graduate teaching, internship, and research work; participate in student recruitment, registration, and placement activities; act as advisers to student organizations; compile bibliographies of specialized materials for outside reading assignments; provide professional consulting services to government or industry; supervise students' laboratory work; maintain and repair laboratory equipment; perform administrative duties such as serving as department head.

51. Suppose for a faculty hire, when do I bring up the possibility of a spousal hire?

You can handle the timing of a spousal hire request in several ways. There is no one right answer for everyone. I used to recommend bringing up the request only once you have an offer and begin formal negotiations. However, I recently spoke with a physical sciences department chair, who shared the following case. His department interviewed a scientist, and during the private interview with the chair the candidate revealed that her partner was also a scientist in a different discipline. She asked whether is was possible to find a position for him. The chair told me he was happy she brought it up at that point in the interview. It didn't impact this search committee's ultimate decision, and it gave the chair time to explore available resources for the partner, if the search committee recommended that the candidate be hired.

So in some cases the question of a spousal hire can be raised during the formal interview. I generally recommend against addressing it in the first communication with the department-that is, in the cover letter-but I have heard of cases where such an early overture has been advantageous for both the candidate and the employer. Whenever you chose to bring it up, you will need to weigh the benefits with the possible negative effects it could have on your candidacy. But if you think creatively, you might even orchestrate a new opportunity for both you and your partner, such as offering to share a faculty line.

52. Explain what is the best way to keep my nerves under control during an interview?

This is actually quite simple-though not always easy-to do. Interviewing will get easier the more you do it, so if you are just about to graduate or are mid-career and haven't interviewed in a while, practice in advance. Do mock interviews with friends, family, and colleagues. If you have access to a university or community career center, check to see if they offer mock interviews. When you attend career fairs, approach first the booths for companies for which you are certain you don't want to work and practice introducing yourself there before moving on to your dream companies. All this practice will benefit you tremendously in easing your nerves and giving you confidence.

Next, prepare. Extensively research the organization, learn their research goals and projects, and, for nonacademic environments, their products, services, customers, and competition. Read its websites, pore through its annual reports, and understand media coverage about it. You can even use LinkedIn to search for the decision-maker (if you know who this person is) and senior members of the company, and read their postings on this site and others. Know the organization, and be able to articulate why you are the best candidate to solve their problems. Be prepared to speak in their language. Refer to the data that you have collected so they know how committed you are to the organization.

Thirdly, prepare for typical and so-called behavioral interview questions by finding them online and practicing answers to these. Get in the habit of being able to answer these questions in a natural, conversational style as opposed to reciting answers from memory. Fourth, go in to the interview with a sense of joy! It is a rare and enjoyable privilege to have a conversation with someone who is passionate about your subjects and with whom you could be a potential collaborator. Such an interview is not a chore. It is a fun enterprise and even though you will maintain your professionalism, you should adopt a mindset that it is an enjoyable activity. Smile. You will notice as you interview that the more you adopt an attitude of enjoyment, the more the interviewer will mirror that attitude right back to you.

Finally, recognize that if you have made it to the interview, the decision-maker is intrigued by something special about you. They would not waste their valuable time interviewing you if they didn't think you were a viable candidate who could deliver greatness. So use this knowledge to give yourself a boost of confidence.

53. Tell me how do I ask for a business card at the end of an interview?

You should ask for the contact information of everyone who interviews you. The information can be in the form of a business card, if they have one. If not, you can jot down names, mailing addresses, phone numbers, and email addresses. You can ask for this information as you conclude the meeting, or you could potentially ask for it at the beginning. In regards to your own business card, you should offer it at the beginning of each interview or individual meeting.

54. Do you know what is Quantum entanglement?

Quantum entanglement is one of the central principle of quantum physics, which means multiple particles are linked together in a way that the measurement of one particle quantum state determines the possible quantum of the other particles

61. Explain what do I do when I receive two equally good offers around the same time, but one is for a short-term job, such as a postdoc, and the other is for a longer-term duration, such as a permanent job in a company?

You will have to make a personal choice. Make sure you have all the information about each offer in order to make an informed decision. Carefully compare the offers analyze the Strengths, Weaknesses, Opportunities, and Threats (SWOT) associated with each position. What strengths will you be able to leverage and expand? What are the position's weaknesses, and can they be remedied? What opportunities will come your way to improve and learn skills, gain access to new networks, and collaborate with professionals? What threats might there be to your career? That is, could you lose time away from what you really want to do? Is it in a location that for one reason or another can't work for you? These questions apply to both short-term and permanent positions.

You might also choose to tell the interviewer that you have received other offers and that you are carefully weighing your options. However, if you do this, your interviewer might think you are employing a negotiation tactic.

62. Tell me at the end of the interview when they ask "do you have any questions for us?", what should I ask?

Your response will depend on the position and the sector, but in all cases, when they ask you if you have any questions, you should definitely have some ready. The interviewer wants to see if you have done your homework about the organization and are committed to them specifically, so feel free to ask questions about current projects, products, or services that you read about in your research. For an academic job, make sure you ask questions about the department: how it interacts with others, or how interdisciplinary research is supported and fostered, for example.

66. Explain by which Newton's may the weight of an object be assigned?

Laws of gravitation

67. What is the device used for measuring the wavelength of X-rays?

Bragg Spectrometer

68. Suppose I don't get the position, is it OK to ask for feedback?

Yes. In fact, I highly encourage you to take this action, for a number of reasons. First of all, you do want to know why you didn't get the job, and often the decision-maker will give you truthful insight. This is especially likely if you networked with her or him before you applied, or when you interviewed for the position you had especially good rapport). The reason you were not selected might have nothing to do with you (perhaps they had to hire someone else for timing or because they are the boss's brother-in-law). Or it might be that another candidate had a superior set of skills and experience. Alternatively, if it was a reason relating to your interview performance, you want to know this so you can remedy it for the future.

Your request for feedback also shows the interviewer that you are interested in their opinion, and, by extension, that you are still committed to the company. So in the course of asking for feedback, be gracious, thank them for their candor, and clearly indicate that you are still interested in working for this organization and hope to help them in a future capacity.

Finally, people respond positively to those who show they want to improve. After all, successful workers seek opportunities to develop skills and improve the circumstances and skills of their team. By sharing your desire to learn how you might have erred in the interview, you demonstrate this important attribute and you keep the door open for you to come back, perhaps for a different job, or perhaps for the same job should the successful candidate not work out.
