What is the difference between the intensity of a wave, and its energy?


The energy but not the intensity io proportional to the frequency.
For monochromatic waves, the two are proportional.

IMHO, this is a misunderstanding. The question concerned the energy of
a _wave_, not of a single quantum (there was no reference to quanta at
all). Generally, "intensity" of a wave simply means the (time-averaged)
energy flow density. Both energy and intensity are unrelated to frequency.
