A person is looking at the flat surface of a transparent hemispher of refractive index `mu-sqrt(2)` . Half of the flat surface is coloured black and half of curved surface is coloured in six equally spaced strips as shown in Figure. Then

A parallel narrow beam of light is incident on the surface of a transparent hemisphere of radius R and refractive index mu=1.5 as shown. The position of the image formed by refraction at the image formed by refraction at the spherical surface only as

A parallel beam of light is incident on the surface of a transparent hemisphere of radius R and refractive index 2.0 as shown in figure. The position of the image formed by refraction at the first surface is :

A right angled triangular prism of refractive index mu_(1) is kept floating on a liquid (surface) having refractive index mu_(2) . The condition such tat light incident normally passes through base of prism as shown in figure.
