Question

what is meant by rectilinear propogation of light ?How can you prove it?​

Answer 1

Explanation:

Rectilinear propagation describes the tendency of Electromagnetic waves (light) to travel in a straight line. Light only deviates from a straight line when the medium it is travelling through changes density. This is called refraction.

Answer 2

Answer:

Light travels in a straight line. This is called rectilinear propagation of light. ... This means that we cannot bend the ray of light to travel through the bent straw. Thus, this activity proves that light travels in a straight line.
