Homework Help: Theories of light

  1. Jun 27, 2006 #1
    # 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?

    F just measured the speed of light, which is a part of all the above.
    It had nothing to do with media.
    My answer would be that it did not test any of those theories.
