This figure shows a light ray travelling from medium with refractive index `n_1` to a different medium with refractive index `n_2` It shows the bending of light ray due to a change in medium which is called 'Refraction'

Which is correct if total internal reflection occurs in medium 1(with refractive index `n_1`)

Options

A. `n_2 gt n_1`
B. `n_2 = n_1`
C. `n_1 gt n_2`
D. TIR does not depend upon refractive index

Answer

C
