Embibe Experts Solutions for Exercise 1: Exercise 1

The speed of light in media $M_1$ and $M_2$ are $1.5\times {10}^8 \mathrm{m} {\mathrm{s}}^{-1}$ and $2.0\times {10}^8 \mathrm{m} {\mathrm{s}}^{-1}$ respectively. A ray of light enters from medium $M_1$ to $M_2$ at an incidence angle $i$. If the ray suffers total internal reflection, the value of $i$ is:

Look at the ray diagram shown, what will be the focal length of the 1^st and the 2^nd lens, if the incident light ray passes without any deviation?
