A light ray is travelling from air to glass. True reflected and refracted rays are perpendicular to each other. If the angle of incidence in air is I the refractive index of glass is

A converging lens forms a real image I on its optic axis. A rectangular galss slab of refractive index mu and thickness t is introduced between the lens and I . I will move

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 i_(2)

A glass sphere of refractive index 1.5 forms the real image of object O at point I as shown in the figure when kept in air of refractive index 1 . If the value of x is kR . Find k

Statement I: A light ray is incident on a glass slab. Some portion of it is reflected and some is refracted. Refracted and reflected rays are always perpendicular to each other. Statement II: Angle of incidence is equal to angle of reflection.
