Angle as rotation of a ray.

Angle OF rotation

Complete angle if a rotating ray after making a complete revolution coincide with the initial position the angle formed is called a complete angle.

a ray of light is incident on a plane miror at an angle of 30^(@) in anti-clockwise direction. Find the angle and sense of rotation of the reflected ray.
