A ray incident at a point at an angle of incidence of `60^(@)` enters a glass sphere with refractive index `sqrt(3)` and it is reflected and refracted at the farther surface of the sphere. The angle between the reflected and refracted rays at this surface is:

Options

A. `50^(@)`
B. `60^(@)`
C. `90^(@)`
D. `40^(@)`

Explanation

We have, refrective index, `mu=(sini)/(sinr)impliessqrt(3)=(sin60^(@))/(sinr)`

Refracted angl, `r = 30^(@)`
The angle between the reflected and refracted rays
`theta=180^(@)-i-r=90^(@)`
