Question

what do you undersant by rectiliner propagation of light​

Answer 1

Answer:

Rectilinear Propagation means tendency of electromagnetic waves or light to travel in a straight line . light doesn't deviate or bends when travelling through a homogeneous medium that means refractive index of the medium remains same throughout; otherwise light suffers refraction. Even though a wave front may be bent the indivisual rays are moving in a straight lines
