Question

Calculate the refractive index of water with respect to glass and refractive index of glass with
respect to water, il speed of light in water and glass is 2.2 108 m's and 2 x 10 m/s
respectively​

Answer 1

c = Speed of light in air or vacuum = 3×108 m/s. μ = refractive index of the medium. So the refractive index of glass with respect to the water is 0.909. So this is the required answer.
