Gamma rays faster?

  1. May 20, 2006 #1
    Since gamma rays are much more energetic, then shouldn't they travel faster. Gamma rays are light, but since they are faster shouldnt they travel faster than c?

    The energy if a wave is given by the frequency of the wave, not by it's speed. Gamma waves are more energetic than visable light waves, so they have a higher frequency, and thus a shorter wavelength.

    As far as we know, gamma rays also travel at exactly c. There are theories (google "loop quantum gravity") that predict gamma rays to be slightly faster.

    There is also DSR or Doubly Special Relativity:

    However DSR remains controversial and speculative.
