Embibe Experts Solutions for Chapter: Wave Theory of Light, Exercise 1: Maharashtra Board-2018

Glass plate of refractive index 1.732 is to be used as a polariser, its polarising angle is ____.

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

State Brewster’s law and show that when light is incident at polarizing angle, the reflected and refracted rays are mutually perpendicular to each other.

Herapathite (iodo sulphate of quinine) is used in the production of _______.

The refractive indices of water and diamond are $\frac{4}{3}$and $2.42$ respectively. Find the speed of light in water and diamond. $\left(c=3\times {10}^8 \mathrm{m} {\mathrm{s}}^{-1}\right)$

If the difference in the velocities of light in glass and water is $0.25\times {10}^8 \mathrm{m}/\mathrm{s}$, calculate the velocity of light in air. Given that refractive index of glass and water with respect to air are $1.5$ and $\frac{4}{3}$ respectively.
