Hello there
the refractive index of glass with respect to water is 9/ 8
The refractive index of water with respect to glass will be
= velocity of light in glass / velocity of light in water
= 2 × 10^8 / 2.2 × 10^8
=2 / 2.2
= 0.9
The absolute refractive index of glass is
= velocity in vacuum / velocity in glass
= 3 × 10^ 8/ 2 × 10 ^8
= 3/2
similarly, the absolute refractive index of water is
= 3 × 10^8 / 2.2 × 10^8
= 30 / 22
= 15 / 11
Thank You
