Question

explain the laws of refraction of light and refractive index. in brief​

Answer 1

Answer:

Laws of refraction states that: (1) The incident ray, the refracted ray and the normal to the interface of two media at the point of incidence all lie in the same plane.... Refractive index of a medium with respect to the vacuum is known as the absolute refractive index.

The incident ray, the refracted ray and the normal to the interface of two transparent media at the point of incidence, all lie in the same plane. ... This law is also known as Snell's law of refraction. N = sin i/ sin r. This constant is also called the refractive index of the second medium with respect to the first.
