OPTICS
REFLECTION OF LIGHT
                  AND
REFLECTION OF LIGHT BY PLANE MIRROR :

Reflection of light :
1. First law of reflection
2. Second law of reflection
Reflection of light by plane mirror :
1. Ray diagram
2. Formation of image by plane mirror
3. Features of image formed by plane mirror
(a) Image is virtual,erect and of the same size of object
(b) Lateral inverted
(c) Relation between size of object and mirror
(d)What happens when a mirror is rotated by an angle
(e) Number of images formed by two inclined plane mirror
etc.
