Deviation OF ray and Mirror

A hollow sphere rolls without slipping on plane surface. The ratio of kinetic energy of rotation to the total kinetic energy is

Angle as rotation of a ray.

Rotation OF incident ray and mirror|| image formation by plane mirror|| field OF view

A light ray I is incident on a plane mirror M .The mirror is rotated in the direction as shown in the figure by an arrow at frequency (9)/(pi) "rev"//"sec" ,The light reflected by the mirror is received on the wall W at a distance 10m from the axis of rotation .When the angle of incidence becomes 37^(@) find the speed of the spot (a point) on the wall?

The reflecting surface of two intersecting flat mirrors are at an angle theta (0^(@) lt theta lt 90^(@)) . As shown in Figure. For a light ray that strikes the horizontal mirror, the emerging ray intersects the incident ray at an angle beta . If one of the mirrors is rotated at (d theta)/(dt) = 1^(@)//s , then the angle beta changes aat the rate of
