first radiation constant
description
The constant $\textit{First Radiation Constant}$ is defined in Planck's radiation law about the dependence of the spectral density of various radiation variables on the wavelength of the electromagnetic radiation and the absolute temperature of the black emitter. This is composed of the product of twice $Pi$ times Planck's quantum of action multiplied by the square of the velocity of light.
