Speed of light = 2x10^8
Find refractive index of medium ??
chetan3216:
The refractive index of a substance is the ratio of the velocity of light in vacuum to the velocity of light in the substance. The velocity of light in vacuum is 3.00 • 10^8m/s, and the speed of light in glass as given, converted to meters is 2 • 10^8m/s, hence the refractive index of glass is 3/2 or 1.5 (10^8 cancels out).
