Rayleigh–jeans law formula
WebJan 16, 2014 · The energy density (i.e., the energy per unit volume) is therefore given by a relation known as Rayleigh-Jeans' law. The expression is valid for but incorrect for , as it predicts that in this case the energy density should become infinite. This physically incorrect property of the equation would lead to what has been termed “UV catastrophy". 16.
