    That is also only for particles with mass and are stationary.

    For light, this equation has to be used instead: E = pc.

    When I said "speed of sound", I was referring to "speed of sound in air" which I said previously in my comment. Be specific probably to clear up misconceptions and deter super critical people like me, I guess.
