Question

light enters frim water into glass plate the refractive index of glass are 3×10^8 m/s and 2×10^8m/s respectively the refractive index of water with respect to air is

Answer 1

Answer:

Refractive index of water with respect to glass is 1.5 .

Explanation:

Refractive index of water with respect to glass = speed of light in glass / speed of light in water.

= 3 x 10^8 / 2 x 10^8

= 1.5
