WebSo let me just substitute. If we substitute we get three times 10 to the power eight, that's the speed of light in vacuum, meters per second, divided by one point five. Refractive index by the way has no units. And if you divide it, see what you get. You get three divided by one point five so we get two times, three by one point five is two ...
