Refractive index of water w.r.t air = 4/3
Refractive index of glass w.r.t air = 3/2
Therefore, refractive index of water with respect to glass
= Refractive index of water / Refractive index of glass
= (4/3) / (2/3)
? = 8 / 9
Also, refractive index of glass with respect to water
= Refractive index of glass / Refractive index of water
= (3/2) / (4/3)
? = 9/8
Refractive index of water w.r.t air = 4/3
Refractive index of glass w.r.t air = 3/2
Therefore, refractive index of water with respect to glass
= Refractive index of water / Refractive index of glass
= (4/3) / (2/3)
? = 8 / 9
Also, refractive index of glass with respect to water
= Refractive index of glass / Refractive index of water
= (3/2) / (4/3)
? = 9/8
