What does the frequency of a photon actually mean?

  1. Sep 23, 2005 #1
    Say you have one photon travelling through free space.

    It has its energy level with its corresponding wavelength and frequency.

    What does the frequency mean? What is it doing x amount of times per second?

    Also, the same goes for the wavelength.

    Electromagnetic waves moving through a vacuum, when v = c, can be described as velocity=speed of light/wavelength.

    When light travel from one medium to another, frequency remains more or less the same, but wavelength and/or speed changes.

    Awesome, that was sort of what I was thinking. Thanks for the clarification.

    More or less? Frequency is most certainly invariant, conservation of energy makes this so :wink: .

    It's ok, I'm not interested.
