Question

What is Rectillinear Propagation of light with example?​

Answer 1

Answer:

In an homogeneous transparent medium light travel in a straight line and this is know as rectilinear propagation of light .

Examples - sun rays entering a dark room through a small opening appear to travel in a straight line. light from torch , headlights of car , etc

Answer 2

$\rightarrow\huge\text{Answer}$

☛Rectilinear propagation of light refers to the propensity of light to travel along a straight line without any interference in its trajectory. When light travels through a medium, say air or water, it follows a straight line. ... Another example of rectilinear propagation of light involves the formation of shadows.

☛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.
