Answer:
The refractive index of glass ng is 1.52 and refractive index of water nw is 1.33. Since the refractive index of glass is higher than the water, the speed of light in water is faster than the speed of light through glass. ... The refractive index provides a measure of the relative speed of light in different media.

(a) Laws of refraction :
(i) Angle of incidence is equal to the angle of reflection (∠i = ∠r)
(ii) The incident ray, the refracted ray and the normal lie on the same plane at the point of incidence.
(b) Refractive index of water is 1.33 means that speed of light in air is 1.33 times faster than in water.
