If the speed of light in a medium is 2 x 10 m/s, what is the absolute referactive index of themedium. (velocity of light in vacuum = 3 X 108 m/s) |

Answer» Answer: Refractive INDEX = Speed of LIGHT in AIR (vacuum)/speed of light in GLASS (medium) Speed in vacuum/air = 3 X 108m/s Speed in medium/glass = 2 X 10m/s Refractive index = 3 X 108/2 X 10 = 324/20 =16.2 |
