    In the derivation of plank's equation on blackbody radiation, the radiation within the cavity must form standing waves and thus each frequency has a certain number of possible modes.

    However, I have no idea why the radiation has to form standing waves. Why does the electric field have to be zero?
    I'll be grateful if anyone can enlighten me on this. Thanks!


    I know not with what weapons World War III will be fought, but World War IV will be fought with sticks and stones.

    hmm am not sure if i gut what u mean by standing waves,..my knowledge is that an inclines wave (photon) when it reaches the internal cavity it reflected inside bare times as zig zag lines..
    so there is not raidiations..
    am not sure wha u mean then a standing waves..?
