# Foucault’s experiment to measure the velocity of light supported: 1)Corpuscular theory 2)Wave theory 3)Photon theory 4)Electromagnetic wave theory It cannot be Corpuscular theory because it said that the velocity of light in a denser medium is greater than that in a rarer medium. It however supported wave theory as it said that the velocity of light in a denser medium is less than that in a rarer medium. But the experiment does not support photon theory because we do not consider the particle nature of light. But I don’t know whether it supported the Electromagnetic wave theory. Could anyone clear my doubt?
