The speed of light in air is 3 ?10 m s/, whereas that of the speed of light in water is 2.6 8 ? 10 . What is the refractive index of water with respect to air? Share with your friends Share 0 Anshu Agrawal answered this Dear student, Speed of light in vacuum = 3.0×108 m/s Speed of light in water = 2.26×108 m/s Refractive index of water = ? We know that Refractive index of water = Speed of light in vacuum Speed of light in water Refractive index of water = 3.0×1082.26×108 =1.32 Regards 0 View Full Answer Charvi answered this Speed of light in air = 3 × 10^8 Speed of light in water = 2.26 × 10^8 Refractive index of water = Speed of light in air/speed of light in water = (3 × 10^8)/(2.26 × 10^8) = 1.32743363 ....Ans 1
