Question

A ray of light passes from glass having a refractive index of √3 into air. The angle of incidence for which the angle of refraction is twice of angle of incidence, is

Answer 1

sorry bro I don't have this question answer

Answer 2

Answer:

π/6 =30°

Step-by-step explanation:

As per the Question:-

Light ray is travelling from glass to air

so mu value for glass is √3 for Air it is 1

also given , r = 2i

from Snell's Law:-

mu1 sini = mu2 sinr

√3 sini = sin2i

√3 sini = 2 sinicosi

√3/2 = cosi

i = π/6 (or) 30°

And the Question is Done
