Question

the optical density of medium A is more than the optical density of medium B​

Answer 1

Answer:

Optical density of a medium depends on Velocity of light in that medium.

Explanation:

The speed of light depends on the characteristics of the medium on which it is incident; the optical density of the medium influences the speed of light to a great extent.

Optical density of the medium refers to the sluggish tendency of the atoms of a material to retain the energy absorbed from the electromagnetic wave in the form of vibrating electrons before being re-emitted as an electromagnetic disturbance. The speed of electromagnetic waves in a material with higher the optical density will be slow.

Hence, Optical density of a medium depends on Velocity of light in that medium.
