Show that a ray of light reflected from a plane mirror rotates througha an angle 2theta when the mirror is rotated through an angle theta about its axis perpendicular to both the incident ray and the normal to the surface.

A light ray is incident on a plane mirror, which after getting reflected strikers another plane mirror, as shwon in figure. The angle between the two mirrors is 60^(@) . Find the angle 'theta' shown in figure.

Fig. shows an incident ray AO and the normal ON on a plane mirror. The angle which the incident ray AO makes with mirror is 30^@ . Draw the reflected ray

The view in the figure is form above a plane mirror suspended by a thread connected to the centre of the mirror at a point A . A scale is located 0.75m (the distance form point A to point P ) to the right of the centre fo the mirror. Initially, the palne of the mirror is parallel to the side fo the scale, and the angle of incidence of a light ray which is directed at the centre of the mirror is 30^(@) . A small torque appleid to the thread causes the mirror to turn 11.5^(@) away form its initial positon. The reflected ray then intersects the scale at point Q . The distance form point P to point Q on the scale is
