Question

state the laws of refraction give the meaning of refractive index​

Answer 1

1.
sini / sinr = constant ( n21)

2.
incident ray ,parallel ray and normal lie on the same plane


REFRACTIVE INDEX

THE SPEED OF PARTICLE CAME TO NEW MEDIUM CHANGES TIMES TO THE SPEED OF PARTICLE IN PREVIOUS MEDIUM.

REFRACRIVE INDEX OF GLASS RESPECT TO AIR ,= VELOCITY IN AIR ,/ VELOCOTY IN GLASS

Answer 2

Answer:

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