Hi
I believe the anomalies found in mathematical models of photoelectric emission and black-body radiation were behind the birth of quantum mechanics. I understand the photoelectric emission but I'm having trouble with Rayleigh's law about black-body radiation. What was exact wrong with it? Was the wrong that according to the following formula as the wavelength becomes shorter, the intensity increases but experimentally this wasn't the case?
[latex]I(\lambda )=\frac{2\pi ckT}{\lambda ^{4}}[/latex]
Please help me. Thank you.
Regards
PG
