Embibe Experts Solutions for Chapter: Wave Optics and Interference, Exercise 1: Odisha Board-2018

The refractive index of a medium is $\sqrt{3}$. When light travels from air to that medium, the Brewster's angle (in degrees) will be _____.

Describe Young's double-slit experiment and derive the expression for the fringe width.

In Young's double-slit experiment, the fringe width is $0.1 \mathrm{mm}$ when light of wavelength $600 \mathrm{nm}$ is used. Calculate the fringe width when the entire apparatus is immersed in a medium of refractive index $\frac{4}{3}$ by keeping the source of light in air.

Discuss Huygens' principle. Prove the laws of reflection of light using this principle.
