How does super position not violate conservation of energy?

  1. Jun 10, 2012 #1
    according the principle of superposition, a wave with a certain amplitude superposed with a similar wave will yield a wave with 4 times the amount of energy.

    This would be double the combined energy of the original 2 waves. Assuming 2 point wave sources are perfectly in phase; and there is no destructive interference, wouldnt this violate energy conservation?

    hmmm..... is there something wrong with my phrasing of the question?

    Original waves energy: A^2 Superposed waves energy: (2A)^2 = 4A^2
