Question

What is refractive index?
The ratio of speed of light i
medium.
State Snell's law
The ratio of sine of the ang​

Answer 1

Answer:

Ratio of the sine of angle of incidence to the sine of angle of refraction is Snell's law. Brewster's angle is an angle of incidence at which polarized light rays transmit through a transparent dielectric surface, without any reflection. Refractive index is the ratio of speed of light in two different medium

• In optics, the refractive index of a material is a dimensionless number that describes how fast light travels through the material. It is defined as where c is the speed of light in vacuum and v is the phase velocity of light in the medium
