The speed of light in air
WebSo in air, we have c divided by index of refraction of air and if we look that up in table [25.1], index of refraction in air is 1.000293 so we plug that in for n here and the speed of light is 2.998 times 10 to the 8 meters per second and we end up with 2.997 times 10 to the 8 meters per second is the speed of light in air. The speed of light ... WebSep 7, 2016 · The index of refraction of air for optical frequencies is around 1.0002, so the speed of light in air is about \$2.9985\times10^8\$ m/s, as compared to \$2.9979\times10^8\$ m/s in vacuum.
