| May 28, 2018 at 7:56 | comment | added | Jepsilon | Assuming monochromatic light beams, then the only factors that effect the speed are the medium's permittivity and permeability since $c=\frac1{\sqrt{\varepsilon\mu}}$. With regards to different wavelength you would need to consider dispersion relations and group velocities | |

| May 28, 2018 at 6:02 | comment | added | Peter Diehr | This isn't the case for light: the index of refraction varies by wavelength; and is n=c/v for that media. This accounts for the dispersion of light. The effect is negligible in air and non-existant in vacuum. | |
