Text: Radiation is emitted intermittently in bundles consisting of integral multiples of a fundamental amount. E=hv where h is Planck's Constant 6.6x10^-27 ergs sec. and v is the frequency of the radiation. E = C/wl5(ec/wlT-1) where C is a constant, wl the wave length, e the base of the natural logarithms, c another constant, and T the absolute temperature. h = 6.57x10^-34 joule sec. The size of a photon (quanta) depends upon the frequency of the radiation and is expressed in units of energy as hF, when h is Planck's Constant and F is frequency in cycles per second.
