Nuclear scientist Interview Question:

Tell me what is Parallax and Distance Measurement?

Submitted by: Muhammad

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.
