- The speed of light in vacuum is a fundamental constant, independent of temperature, pressure, or density. - The speed of light in a medium depends on the medium's refractive index. - The refractive index of air (a gas) depends on its physical state parameters like temperature, pressure, and density.
The speed of light in air depends on,
