Ultraviolet Led
Ultraviolet Led
Why was Black Body radiation confusing to classical physicists?
I don't understand why it led to quantum mechanics... Mostly I don't understand the Ultraviolet catastrophe or the Fourier mode.
Can someone explain both the initial laws that explained these kind of things (the classic ones)
and then what the ultraviolet catastrophe is?
Thank you!
Oh, heres my take on it
before quantum mechanics and the Bohr model the atoms arrangement of electrons were not known. They figured they just circles the nucleus but it turns out that any accelerating charge emits radiation. The atom should therefore be constantly emitting radiation and hence the electron should be losing momentum and slowly spiral in towards the center of the nucleus. If the world worked this way there would be no stable atoms and we wouldn't exist. The idea of energy levels and quantization eventual fixed this (quantum mechanics)
Ultraviolet catastrophe. The black body spectrum was nice and behaved for long wavelengths...meaning it was nice an predictable. As the frequency of the light increased the temp was predicted to increase and hence the energy. The curve was not linear and it showed that as you approached ultraviolet (May have been another frequency) the intensity would approach infinity. The energy for radiation is proportional to temperature to the fourth power therefore..if this would correct high frequency radiation would dominate everything. But it doesn't...therefore the model was incorrect
