When a plane mirror is rotated through an angle ` theta` then the reflected ray turns through the angle `2 theta` then the size of the image

When mirror is rotated through an angle theta , a reflected ray from it moves through an angle of

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 small angled prism of apex angle A=4^@ and refractive index mu=1.5 is placed in front of a vertical plane mirror as shown in figure. If the mirror is rotated through an angle theta, then the light ray becomes horizontal either after the mirror or after second time passing from the prism in opposite direction. The value theta is

For a fixed incident light ray, if the mirror be rotated through and angle theta (about an axis which lies in the plane of mirror and perpendicular to the plane of incidence), show that the reflected ray turns through an angle 2 theta in same sense.

A mirror is turned through 15^(@) . Through what angle will the reflected ray turn ?

If we turn the mirror by an angle of 20^(@) , the reflected ray will turn through which angle ?

A wheel is subjected to uniform angualr acceleration about its axis. Initially, its angualr velocity is zero. In the first 2 sec , it rotates through an angle theta_(1) , in the next 2 sec , it rotates through an angle theta_(2) . The ratio of theta_(2)//theta_(1) is
