Refractive index of glass with respect to water =speed of light in glass / speed of light in water
=(2×10^8)/(2.24×10^8)
=25/28
For refractive index of water with respect to glass, it is 28/25
Hope it helped u☺️☺️☺️

the refractive index of water with respect to glass = speed of light in glass/speed of light in water
=2×10^8/2.24×10^8=0.89
