Question

refractive index of glass 3/2 where as light travelling from air to glass if angle of refraction 30 degrees find angle of incidence

Answer 1

Answer:

The angle of incidence is 48.95°

Explanation:

According to Snell's Law,

Refractive index, n= sin i/ sin r

=>3/2= sin i/ sin 30

=>1.5 x sin 30= sin i

=>sin i= 3/4

=> i= sin^(-1)[3/4]

=> i= 48.95°
