What Is Rectilinear Propagation?

Rectilinear propagation describes the tendency of electromagnetic waves to travel in a straight line. Light does not deviate when travelling through a homogeneous medium, which has the same refractive index throughout; otherwise, light suffers refraction.

What is rectilinear propagation give an example?

The property of light travelling in a straight line is called as the rectilinear propagation of light. A light source can be seen only if there is a straight-line path between the source and our eyes. Examples: ... Light from torch, headlights of cars, etc. appears to travel in a straight line.

What is rectilinear propagation class 10?

Rectilinear refers to the straight line and propagation means action or process of spreading. Thus, the word rectilinear propagation of light means that light travels in a straight line. ... When light travels from one medium to another then it changes its path in another medium. This phenomenon is called refraction.
