Inside a solid glass sphere of radius R,...

Inside a solid glass sphere of radius `R`, a point source of light lies at a distance `x(xltR)` from centre of the sphere. The solid is surrounded by air of refractive index 1. The maximum angle of incidence for rays incident on the spherical glass air interface directly from the point soure is:

A

`"cos"^(-1)x/R`

B

`"sin"^(-1)x/R`

C

`"cos"^(-1)sqrt(x/R)`

D

`"sin"^(-1)sqrt(x/R)`

Text Solution

Verified by Experts

The correct Answer is:
B
Let `O` be the centre of `A` be the point source for ray incident
at any point `P` t angle have maxmum angle of incidence `i`,
