Question

if the refractive index of water for light going from air to water 1.33 what will be the refractive index for light going from water to air​

Answer 1

Answer:

The refractive index is the ration between seed of in vacuum to the speed of light in medium.

The refractive index of water for light going from air to water is 1.33.

So the refractive index for beam of light going from water to air will be the inverse of 1.33.

n = 1/ 1.33

n = 0.75

Thus the refractive index will be 0.75
