Variable Refractive Index

Q.

The velocity of a certain monochromatic light is $2.25\times {10}^8\frac{\text{m}}{\text{s}}$ to the given transparent medium. Find polarization angle for this medium.

Q.

A ray light is incident at the glass-water interface at an angle i, it merges finally parallel to the surface of water, then the value of ${\mu }_g$ would be

1. (4/3) sin i

2. 1 /sin i

3. 4/3

4. 1
