Answer:
Speed of light in air is 3*10^8 m/s and speed of light in common glass is 2*10^8 m/s. Calculate the refractive index of glass. Answer: Glass refractive index is defined as the ratio between the speed of light in the vacuum and the speed of light in the glass.

Answer:
Light in air is 1.0003 times slower than light in a vacuum, which slows it all the way down from 299,792,458 meters per second to 299,702,547 meters per second. That's a slowdown of 89,911 meters per second, which looks like a lot but is only three ten-thousandths of the speed of light.05-Apr-2016
