Question

Condition of regular reflection of light with example

Answer 1

Regular reflection occurs at the surface of a plane surface like a plane mirror. Reflected rays after regular reflection are parallel.

Diffused reflection occurs at the surface of a rough surface like cardboard. Reflected rays after regular reflection are not parallel.

Note: Laws of reflection are valid in both the cases.

Regular Reflection:

1. Reflection from a polished surface is called regular reflection.

2. parallel rays remain parallel after reflection.

Irregular Reflection:

1. Reflection from a rough surface is called diffuse reflection.

2. Parallel rays do not remain parallel after reflection.
