 A ray of light is reflected on a plane mirror. mirror This is an example of reflection of light.

 The incoming ray is the incident ray.  The outgoing ray is the reflected ray.  The line at right-angles to the mirror’s surface is called a normal.  The mirror in this case is a plane mirror.

reflected ray incident ray normal mirror angle of incidence angle of reflection

 The incident ray, the reflected ray and the normal all lie in the same plane. normal incident ray reflected ray mirror normal incident ray reflected ray mirror

 angle of incidence = angle of reflection normal incident ray reflected ray mirror

Rays from object O become divergent after reflection. mirror O

I is a virtual image. Reflected rays appear to come from I behind the mirror. mirror O I

 Properties of the image formed by a plane mirror 3 virtual 1 behind the mirror 2 of same size as the object 4 laterally inverted mirror object image

The angle between the incident ray and the _______ is called the angle of incidence. normal The laws of reflection state that it is equal to the angle of ___________. reflection

The angle between an incident ray and the mirror is 20 . The angles of incidence and reflection are ____  and ____   70 
