Question

On what two factors does the relative refractive index of two media depend?​

Answer 1

Explanation:

Refractive index of a medium depends upon the refractive index of the surroundings (when you consider the light ray passing from the surrounding into the medium), optical density, wavelength of the light and temperature.

Answer 2

Answer:

here is the answer:

Suppose a light ray travels from medium 1 to medium 2, then the relative refractive index of medium 2 with respect to medium 1 is useful.

Refractive refractive index of medium 2 with respect to the medium 1:

= μ₂₁ = μ₂ / μ₁

The factors on which it depends are:

1. Refractive index of medium 1: μ₁.

This depends on the material and the frequency of light ray.

2. Refractive index of medium 2: μ₂.

This also depends on the material and the frequency of light.

3. The frequency or wavelength or the color of the light/radiation used to measure the refractive index μ₂₁.

4. It depends on the direction of propagation of light rays from medium 1 to medium 2 or the other way round.

We have two relative refractive indices for a pair of media: μ₁₂ and μ₂₁.

They are reciprocals of each other.
