Embibe Experts Solutions for Chapter: Wave Optics, Exercise 1: Exercise

Plane wavefront can be obtained from

On the basis of Huygen's secondary wave principle explain refraction of light and derive Snell's law.

State Huygens' principle and hence explain the construction of spherical and plane wavefront.

With the help of a neat diagram, explain reflection of light from a plane reflecting surface on the basis of wave theory of light.

Explain refraction of light on the basis of wave theory. Hence prove the laws of refraction.

Explain the terms plane of polarisation and plane of vibration.

What do you mean by polarisation of light? How will you distinguish between polarised and non polarised light?

By reflection how we can get plane polarised light? What is Brewster's law? Prove that if light is incident on plane transparent slab at angle of polarisation, then reflected and refracted rays are perpendicular to each other.
