Answer 2

Explanation:

• Total internal reflection of light is the process in which the light ray completely reflected within a medium such as water or glass from the surrounding surfaces back into the medium.

• The condition for the total internal reflection area as follows :

1. The ray of light must travel from denser medium to rarer medium but not from rarer to denser.

2. The angle of incidence must be greater than critical angle. Critical angle is given by : $\theta=\sin^{-1}(\dfrac{n_{rarer}}{n_{denser}})$
