Regular and Diffused Reflection-
When parallel rays of light are incident on plane mirror then reflected rays are parallel to each other in any specific direction. This type of reflection is called Regular reflection. Regular reflection occurs by plane mirror or other smooth and bright surface.
Irregular Reflection- when the incident rays fall on a rough surface they are parallel to each other but after reflection they are no longer parallel but are reflected in different directions. This type of irregular reflection is called diffusion reflection. Diffusion reflection is caused by irregular surface of the reflector. Diffused reflection occurs on the irregular surface such as. book, surface of table, etc. The presence of light under a tree and inside the room is because of diffused reflection.
