Told you .
Explanation:
Light is form of energy - The rest can be deduced from this .
Answer:
Reflection of Light: The phenomenon of bouncing back of light into the same medium by the smooth surface is called reflection.
Incident light: Light which falls on the surface is called incident light.
Reflected light: Light which goes back after reflection is called reflected light.The angle of incidence: The angle between the incident ray and the normal.
An angle of reflection: The angle between the reflected ray and the normal.
Mirror: The surface which can reflect the light is a mirror.
Plane Mirror: If the reflecting surface is a plane then the mirror is plane.Spherical Mirror: If the reflecting surface is part of the hollow sphere then the mirror is a spherical mirror.
The spherical mirror is of two types:
Convex mirror: In this mirror reflecting surface is convex. It diverges the light so it is also called a diverging mirror.
Concave mirror: In this mirror reflecting surface is concave. It converges the light so it is also called converging mirror.
