Question

If the critical angle is 45o

, what is the refractive index ?​

Answer 1

Answer:

the ratio of sini to the sinr is equalti mne

Is constant called refractive index

Answer 2

Answer:

Refractive Index is n = c/v

Here c is the velocity of light in vacuum and v in the medium.

Since,

$n = \sqrt{2} \\ v = \frac{c}{ \sqrt{2} }$
