What is the relation between wavelength and period of a wave?
www.as.utexas.edu(a continuous spectrum). How bright the light at different wavelengths is depends on the temperature of the solid. Hotter solids emit more light of all wavelengths, but they especially emit more short wavelength (blue and violet) light. When gasses are heated they emit only certain wavelengths of light (an emission line spectrum).
