WebIn vacuum the speed of light is c = 2.99792458 x 10 8 m/s This vacuum speed of light, c, is what the statements from relativity describe. Whenever light is in a vacuum, its speed has that exact value, no matter who measures it. 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. ... In the case of "ratios between speeds" a value of n<1 in ultraviolet range seems to be very unrealistic. \$\endgroup\$ – Martin Rosenau. …
