Question

Explain how materials are classified as transparent, translucent, and opaque.

Answer 1

Depending on the way the materials transmit light, they can be classified into three groups:
(1) Transparent material
(2) Translucent material
(3) Opaque material

1. Transparent material
A material that allows light to pass through it is called transparent material.
Example: Air

2. Translucent material
A material that partially allows light to pass through it is called translucent material.
Example: Butter paper

3. Opaque material
A material that does not allow light to pass through it is called opaque material.
Example: Wood
