They have a wavelength of maximum intensity described by Wien's (VEENZ) displacement law.
Historically, it was believed that these objects could be modeled as a cavity with equally likely modes that increased with frequency. The fourth power of temperature is proportional to the flux emitted by one of these according to the Stefan-Boltzmann (STEF-on BOLTS-mon) law. They have a wavelength of maximum intensity described by Wien's (VEENZ) displacement law. The ultraviolet catastrophe describes the breakdown of the Rayleigh-Jeans Law governing radiation from these entities. For 10 points, name these objects that absorb all incoming energy.
