7 On the Quantum Theory of Radíationf

Abstract:

THE formal similarity of the curve of the chromatic distribution of black-body radiation and the Maxwell velocity-distribution is too striking to be hidden for long. Indeed, already Wien in his important theoretical paper in which he derived his displacement law p= v'f (v/T)(1) was led by this similarity to a further determination of the radiation formula. It is well known that he then found the formula p= ov” e-wist,(2) which is also nowadays accepted as being correct as a limiting law for large values of v/T (Wien's radiation law). We know nowadays that no considerations based on classical mechanics and electro-dynamics can give us a usable radiation formula, and that classical theory necessarily leads to the Rayleigh formula 2=—y^ T. 3 p= Ev (3)
