Ok. Can somebody please explain to me about black bodies, and why classical physics thought there would be infinite intensity for smaller wavelengths? And is there a wavelength where intensity is zero, or is the Intensity = 0 an assymptote...and why?
Also, from the student's guide to HSC physics it says:
"Planck resolved this problem with his hypothesis of quantised radiation which explained the experimental data, stating that radiation could only occur in small packets which he called “quanta”. The energy contained within a single quanta is dependant only on the frequency of the radiation according to the formula E = hf. Further, the vibration states of atoms in the black body cavity were also quantised, meaning that they could only have specific discrete frequency values. Since energy is only emitted when these atoms change vibrational states moving to a less energetic state, the energy released is also quantised."
I don't get how Planck saying that EMR occuring in quanta and not waves explains the obserations observed? Why would the light as packets of energy make any difference?
