Question

Pls explain how to solve this question

a ray of light is incident at 60degree on glass Air interface. Then light ray Will

(mu =√2,mu=1)

Answer 1

Here in this situation, both conditions of total internal refraction are satisfied as:-

1. Light Ray is traveling from denser(glass) to rarer( air).
2. The angle of incidence ( in denser medium) is greater than the critical angle for glass- air inference (~ 42°). Here in this case angle of incidence is 60°.
