How do you find the refractive index of a diamond?

The refractive index of a diamond is about 2.4. To calculate the refractive index you divide the speed of light in a vacuum by the speed of light in

How do you find the refractive index of a solid?

The refractive index of the test plate, referred to that of the surrounding medium, can be obtained by measuring the optical-path differences introduced between a ray through and a reference beam outside the plate by two successive rotations, which change the angle of incidence.

How do you find the refractive index of Class 10?

The refractive index is the measure of bending of a light ray when passing from one medium to another. It can also be defined as the ratio of the velocity of a light ray in an empty space to the velocity of light in a substance, n = c/v.
