The refractive index of glass with respect to water is 1.125. If the speed of light in water is 2.25x 108 m/s, then calculate the speed of light in glass.

so refractive index of 2 wrt 1 medium=
refr index of glass wrt water=1.125=vel of light in water/vel of light in glass
vel of light in glass=2.25x108 /1.125=2x108
