So energy must be an integral value in terms of h*f, but f can be whatever? I was under the impression that frequency could be integral values in terms of the Planck length, i.e., it couldn't be 2.3 Planck lengths / s. This is because the .3 Planck lengths has no meaning, as 1 Planck length is...
I guess this is supposed to be here... I dunno. Anyhoo, I understand this concept intuitively, but why do frequencies have to have integer values? Is that true of all waves, or just electromagnetic waves? Could a wave have 33.43 Hz, for example? :cry: Please explain!
