A narrow parallel beam of light falls on a glass sphere of radius R and refractive index mu at normal incidence. The distance of the image from the outer edge is given by-

AN unpolarised beam of light is incident at the polarising angle on the surface of a transparent medium of refractive index 1.6. The angle of refraction in the medium is

Figure shows a transparent hemisphere of radius 3'0 cm made of a material of refractive index 2.0. (a) A narrow beam of parallel rays is incident on the hemisphere as shown in the figure. Are the rays totally reflected at the plane surface ? (b) Find the image formed by the refraction at the first surface. (c) Find the image formed by the reflection or by the refraction at the plane surface. (d) Trace qualitatively the final rays as they come out of the hemisphere.
