Review Of Physics Behind The Speed Of Light Ideas . Web the speed of light in a vacuum is a fundamental physical constant, the currently accepted value of which is exactly 299,792,458 metres per second, or about 186,282 miles per second. The speed of light depends strongly on the type of material, since its interaction varies with different atoms, crystal lattices, and other substructures.
