Planck's Theory

Question

Planck's theory of quantized oscillators leads to an average energy

E=W/[e^(W/kT)−1]

where W and k are constants.

Approximate E with the first two nonzero terms of the Taylor polynomial when kT>>W

E ≈ ____

(Hint: If x>>y, then y/x ≈ 0.)

Answer 1

Hello Haley heres is the answer if you solve the Talyor's expansion sereis from the planck Quantum theory you will get

E=kT which is the average energy of the each radiationwhich is equal to plancks equation

E=hv
