Find the angle of incidence of the ray shown in Fig. for which it passes through the pole, given that `MI|\|CP`.

A ray of light strikes a plane mirror at an angle of incidence 45^@ as shown in Figure . After reflection,l the ray passes through a prism of refractive indes 1.5 whos apex angle is 4^@ . Through what angle must the mirror be rotated it total deviation of the ray be 90^@ ?

In figure shown find the angle of incidence of the light ray on face AB of the prism for which light will reach face AC at incidence angle 60^(@) . [90^(@)]

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.
