What is the "average energy" in the equation that Planck used to fix the Rayleigh-Jean classical prediction on blackbody radiation? 
 
(A) hν/(e^(hν/(k_B T))-1) 
(B) 8πν/c^3 
(C) k_B T 
(D) nhv - correct answer (A) hν/(e^(hν/(k_B T))-1) 
 
As seen in the image, if the 8π^3/c^3 terms are ignored, the simplified expression is the answer.
