Class 8 Physics Light Regular and Diffused Reflection

Regular and Diffused Reflection


Note: The Blue color rays are Incident Rays, the Black are the Normals and the Red color rays are the Relected Rays.

Regular Reflection: When light falls on a smooth uniform surface (like a mirror), all the parallel incident rays are reflected perfectly parallel. This is called Regular Reflection

Diffused Reflection:  When light falls on a rough surface (like a stone, your body, your clothes etc), all the parallel incident rays are not reflected parallel to each other. This is called Diffused Reflection. 

Note: Both Regular and Diffused Reflection obey the Laws of Reflection. Diffused reflection is caused by irregularities in the reflecting surface and not due to the failure of Laws of Reflection.
