Question

define refractive index. write it's slunt if the refractive index of glass w.r.t to water is 8/5 there for active index of water with respect to diamond 5/12 find the refractive index of diamond with respect to glass

Answer 1

26.6 is the correct answer

Answer 2

define refractive index.

Refractive index :

Refractive index, also called index of refraction, measure of the bending of a ray of light when passing from one medium into another.

If i is the angle of incidence of a ray in vacuum (angle between the incoming ray and the perpendicular to the surface of a medium, called the normal) and r is the angle of refraction (angle between the ray in the medium and the normal), the refractive index n is defined as the ratio of the sine of the angle of incidence to the sine of the angle of refraction; i.e., n = sin i / sin r.

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.
