He explained the origin of the Fraunhofer lines in the spectrum of sunlight and suggested that at a given temperature the ratio of the emissivity and the absorptivity of any solid surface is the same irrespective of wavelength when the radiation is in equilibrium with the solid surface.

FTP name the scientist who also helped Bunsen discover cesium and rubidium and has two laws of electric circuits that also bear his name.
