What do you mean by refractive index of two mediums


Anonymous: It is a property of medium thAt at what extent does it bend the light
rrrrrrr3: actually it never bend due to change in velocity a ray light is deviated from its path when it falls on the surface of second medium
rrrrrrr3: deviation from light from its path considered as bending
rrrrrrr3: of*
Anonymous: Ya ya due to change in velocity light bends
Anonymous: And change in velocity is due to medium
Anonymous: So bending is due to medium

Refractive index, also calledindex 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 ofrefraction (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 = sini / 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.
