Question

the absolute refractive index of water is 4/3 and absolute refractive index of glass is 3/2 find out the relative refractive index of water with respect to glass and glass with respect to water.

Answer 1

And if it helped please mark as brainliest

Answer 2

n(glass)=velocity in vacuum /velocity in glass

n(water)=v in vacuum /v in water

Hence -

V in glass= v in vacuum * 2/3

V in water =v in vaccum*4/3

The answer

is

V in water /v in glass

9/8
