This is my understanding of the black body radiation: a black body is heated. The energy from the heat causes the electrons in the body to oscillate, so they will emit electromagnetic waves. If we plot the intensity of radiation against the emitted frequencies, we'll see that beyond a certain frequency, the intensity is decreasing for higher frequencies. Here are my questions assuming the above description is correct:

1. Is it true that there are equal number of electrons emitting each frequency or there are less electrons emitting higher frequencies?

2. Is intensity of radiation related to a wave's amplitude? or is it related to number of electrons emitting a certain frequency?

3. If there are equal number of electrons emitting each frequency, is it then the amplitude of the waves which demands a higher frequency wave carrying more quanta of energy?
