Question

A ray of light is incident on a medium with angle of incidence, i , and refracted into a second medium with angle of refraction, r . The graph of Sin( i ) vs Sin( r ) is given. Refractive index of second medium with respect to first medium is ____? ​

Answer 1

Answer:

1/root 3

Explanation:

Tan 30 = sin i/ sin r

(Tan 30= 1/root 3)

and sini/sinr= refractive index of medium 1 wrt 2

therefore,,  RI=1/root3        ANS........
