Question

What is mean by refractive index and absolute refractive index

Answer 1

Refractive index is defined as ratio of sine of angle of incidence to sine of angle of refraction. It is denoted by n or μ. Thus, refractive index is given by, Absolute refractive index: When the light is going from vacuum to another medium, then the value of refractive index is called the absolute refractive index.
