Unformatted text preview: n = 0, 1, 2, where f is the frequency of the oscillation and h is a universal constant. E 0 Energy Levels smooth & continuous Classical E 0 Energy Levels quantized Planck New BlackBody Calculation: The prediction for (T,f) still consists the following two pieces: ( ) > < = E V df f N df f T ) ( ) , ( .

Classically <E> = kT, but Plancks assumption that the energy levels are quantized changes <E>. Birthday of Quantum Physics! Quantum States...
