Question

Differentiate between regular and diffused reflection.draw diagram to show the two types of reflection.

Answer 1

regular reflection - reflection of light that takes place from plane, shiny or polished surface
diffused - reflection that takes place from non Shiny, non polished or irregular surfaces

Answer 2

When all the reflected rays from a given smooth surface are parallel for parallel incident rays, the reflection is known as regular reflection.
When for a given set of incident parallel rays, the reflected rays do not remain parallel to each other, the reflection is known as diffused or irregular reflection.
Regular reflection
1. It occurs when parallel beam of incident rays remain parallel after reflection.
.2. Occurs from smooth surfaces like mirror, silver spoon etc.
Irregular reflection
1. It occurs when parallel beam of incident light doesn’t remain parallel after reflection.
2. Occurs from rough surfaces like wood, table, door, book etc.
