Is Mass = Frequency ?

  1. Sep 27, 2007 #1
    Hey, can anyone shed any light on the significance of:
    E=mc^2 and E=hv so mc^2=hv or m=(h/c^2)v (using v as frequency)

    So mass = a constant (h/c^2) * frequency

    What does it mean practically that a mass is equivalent to a frequency ?

    Photon has no mass, E=mc^2 does not apply for photons then.
