Answer to Question #95442 in Mechanics | Relativity for Mwanje

Question

define the term parallax

Answer 1

Parallax is the apparent displacement or the difference in apparent direction of an object as seen from two different points not on a straight line with the object especially: the angular difference in direction of a celestial body as measured from two points on the earth's orbit.

The term “parallax” refers to the apparent movement of objects when viewed from different positions. The everyday example of this is seen driving on the highway - when you look out the window, electrical poles near the road seem to zoom past, while trees in the distance appear to slowly drift by.
