Refractive index of glass with respect to water is 1.125. If the absolute refractive index of glass is 1.5, find the absolute refractive index of water.
1.33
Here, the refractive index of glass with respect to water
i.e., wμg = 1.125 and absolute refractive index of glass μg=1.5
We know that
wμg=aμgwμg=1.51.125=1.33
