"a black body could emit radiation only at discrete frequencies"
I think, black bodies can emit radiation at all frequencies. However, Planck purposed that the radiation does so in a discrete fashion. Recall his formula E=nhv (h = 6.626x10^-34 J s) (v (nu) = the frequency) (n is a postive integer). Notice that energy can increase either with v (nu) continously or discretely with n. The electromagnetic spectrum is continous. (For all intents and purposes I am ignoring the debate of whether the world is actually continous. Mathematicians need not quible.)
