How is refractive index of any medium 'A' with respect to a medium 'B' related to the
speed of propagation of light in two media A and B? State the name of this constant when
one medium is vacuum or air.
The refractive indices of glass and water with respect to vacuum are 3/2 and 4/3
respectively. If the speed of light in glass is 2 x 10^8k m/s, find the speed of light in ()
vacuum, (ii) water.
