There is a spherical glass ball of refractive index `mu_(1)` and another glass ball of refractive index `mu_(2)` inside as shown in figure . The radius of the outer ball is `R_(1)` and that of inner ball is `R_(2)`. A ray is incident on outer surface of the ball at an angle `i_(1)`,

Find the value of `r_(2)`

A ray of light is incident on a glass slab of refractive index 1.5, making an angle of 40^(@) with the surface. The angle of refraction in glass is

A light ray is incident on a glass sphere of reflective index mu = sqrt3 at an angle of incidence 60^(@) as shown in Fig. Find the angles r, r^(') e and the total deviation after two refractions.

A ray of light is incident on the surface of plate of glass of refractive index 1.5 at the polarising angle. The angle of refraction of the ray will be

A ray of light passing through the medium of refractive index mu_(1) is incident on the surface of separation of another medium of refractive index mu_(2) . A part of the ray is reflected and another part is refracted. What should be the angle of incident so that reflected ray and the refracted ray are at right angles to each other?
