Abstract
The proportionality between black-hole entropy and area is derived from the minimal assumption that black holes are classical thermodynamic objects. The relationship between the classical and quantum formulas is shown to be similar to that of blackbody radiation. Classical thermodynamics is shown to imply certain characteristics for classical waves which are normally thought to be quantum mechanical in origin.
