Question

Define: Refractive index of a medium in terms of velocity of light.​

Answer 1

Explanation:

• Refractive index, also called index of refraction, measure of the bending of a ray of light when passing from one medium into another. ... Refractive index is also equal to the velocity of light c of a given wavelength in empty space divided by its velocity v in a substance, or n = c/v.

Answer 2

Refractive index is defined as the ratio of the speed of light in a vacuum to its speed in a specific medium.

Refractive index is defined as the ratio of the speed of light in a vacuum to its speed in a specific medium.Refractive index is dimensionless. It is a number that indicates the number of times slower than a light wave would be in the material than it is in a vacuum. Refractive index, represented by symbol n, is the velocity of light in vacuum divided by the velocity of light in a medium. The formula of the refractive index is,

n = c/ν

n = c/νwhere

n = c/νwheren = Refractive index.

c = Velocity of light in a vacuum ( 3 × 108 m/s).

c = Velocity of light in a vacuum ( 3 × 108 m/s).v = Velocity of light in a substance.
