If the speed of light in water is 2.25X108m/s and the speed in vaccum is 3X108 m/s . Calculate the refractive index of water.
Speed of light in vacuum = 3.0×108m/s Speed of light in water = 2.25×108m/s Refractive index of water = ? We know that Refractive index of water = Speed of light in water Speed of light in vacuum Refractive index of water = 2.25×1083×108=1.33
