N2 - The discussion on “Radiation” in Section A at the recent British Association meeting in Birmingham was one of profound interest. Some of the remarks made then suggested the investigation which I now describe. Planck’s formula for the emission function Eλ is C2hλ-5 / (e Ch/kλT — 1). This formula represents the observations for short and long waves at various temperatures with considerable closeness; and, if it is the correct expression, it is held by some to prove that the classical equations of dynamics and electrodynamics are at fault. As I do not think the classical equations are in much danger if properly applied, I have endeavoured to trace the dynamical explanation of the experimental data. There must be many formulae which will express the data as well as Planck’s form. In searching for such an expression of dynamical form, I went back to the equations for the motion of a charged sphere which I established on dynamical principles. A clue to a solution very soon appeared, and without further remark, at present, I will state the formula that was tried.
