Energy when two opposite pulses meet

  1. May 4, 2012 #1
    1. The problem statement, all variables and given/known data
    Two pulses moving in opposite direction meet at a point. Both are out of phase. What will happen to their energy?


    2. Relevant equations



    3. The attempt at a solution
    Well i know the string will go blank. Their amplitudes will get cancelled. But what kind of energy will remain? Energy should remain conserved.
    Well when the two pulses meet the string doesnt move up or down so i suppose its purely potential energy but i dont udnerstand this . Potential energy is present when the string is dispalced from its psotion but in this case string is not at all dispalced so how can it have potential energy?

    So perhaps its purely kinetic energy but then again string is not moving...(im confused)
