Question

how is the refractive index of a medium related to the speed of light obtain an expression for Refractive Index of a medium with respect to another in terms of speed of light in these two media​

Answer 1

Answer:

Explanation:

Refractive index compares the speed of light in a particular medium with the speed of light in vacuum. It measures the optical density of a medium. It should not be confused with the mass density of the medium.

Answer 2

$\large\mathcal\red{Explanation✓}$

Refractive Index can be seen as the factor by which the speed and the wavelength of the radiation are reduced with respect to their vacuum values.

$\large\bf\pink{w=civ}$ (where n:refractive index,c=speed of light,v:velocity of light in that medium)

Refractive index of one medium in relation to a second medium is given by the ratio of the speed of light In the second medium to speed of light in the first medium.
