The velocity of light in glass whose refractive index with respect to air is 1.5 is 2×108 ms−1and in certain liquid, the velocity of light is found to be 2.50×108 ms−1. Find the refractive index of that liquid with respect to air.
The velocity of light in glass (μ=1.5) is 2×108m/s and in certain liquid(μ=1.2), the velocity of light found to be 2.50×108m/s. Then the refractive index of the liquid with respect to glass is 0.8
