Question

Defination of Absolute refractive endex.​

Answer 1

Answer:

The absolute refractive index is defined as the ratio of light speed in vacuum to light speed in the chosen medium.

Explanation:

• The absolute refractive index is defined as the ratio of light speed in vacuum to light speed in the chosen medium.
• Never let the absolute refractive index to go below one.
• If c is the speed of light in vacuum and v is the speed of light in the chosen medium, then the absolute refractive index is given as n=cv.
• Any medium's absolute refractive index is always greater than one.
• A substance's refractive index specifies how fast light travels through that material.
• It is the ratio of the speed of light in a vacuum to the speed of light in that medium. It is never less than one.
