a) The process of bouncing back of light rays into the same medium after falling on a smooth or rough surface from the light source is called “reflection of light”.
b) Reflections are of two types :
1. Regular reflection
2. Diffused reflection. Reflection from a smooth and shiny surface is called regular reflection. Reflection from an irregular or uneven surface is called irregular reflection or diffused reflection.
c) Laws of reflection :
There are two laws of reflection.
1. Angle of incidence is equal to angle of reflection.
2. The incident ray reflected ray and normal to the surface are present in the same plane. Incident and reflected rays are on either side of normal.
