Question

classify various material based on optical density​

Answer 1

Materials can be transparent, translucent or opaque based on optical density

Explanation:

Optical density is a term used to denote the propagation of light waves through a material. A higher optical density indicates how much slower the wave travels through that material. The refractive index of the material is an indicator of its optical density.

Diamond is the material that has maximum optical density.

Air has the lowest optical density.

Based on optical density, materials are classified into:

1. Opaque - Does not allow light to pass through
2. Translucent - Partially allows light to pass through
3. Transparent - Allows light to pass through

Answer 2

Explanation:

Optical density is a property of any material which is the amount that the light can pass through or absorb in the material

Based on optical density, materials can be classified into three categories

Transparent

These are material that will allow most of the light to go through them. Any object can be seen through the transparent material

Translucent

Such materials transmit some light, but that light will not be unidirectional rather it will be spread

Opaque

Such materials do not facilitate light to pass through them, as either they will absorb that light or reflect that light
