A light ray is incident normally on a plane mirror. What is the direction of reflected ray? Show it on a diagram.
Draw a diagram to show the reflection of a ray of light using a plane mirror. In the diagram, label the incident ray, the reflected ray, the normal, the angle of incidence and the angle of reflection.
Figure 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°. (a) Find the angle of incidence. (b) Draw the reflected ray and then find the angle between the incident and reflected rays.
State which surface of a plane mirror reflects most of the light incident on it: the front smooth surface or the back silvered surface.
