What would happen if the speed of light were much lower?

WebThe simplest picture is that light always travels at the speed of light. But in a material it travels at the speed of light until it hits an atom. It is then absorbed and re-emitted in the same direction, which takes a small amount of time. The more this happens, the slower the effective average speed. WebFeb 20, 2024 · There are many mysteries of physics for which you can find explanations online and some of those explanations are wrong. In this video, Fermilab’s Dr. Don Lincoln takes on the mystery of why light travels slower in water and glass. He lists a few wrong explanations and then shows you the real reason this happens.
