Planck's law ( by the Frequency)

Description

Planck’s law describes the electromagnetic radiation emitted from a black body at a certain temperature. Radiance and spectral radiance are measures of the quantity of radiation that passes through or is emitted from a surface and falls within a given solid angle in a specified direction. Planckian spectral radiance can be measured by the frequency of the radiation.
