BRAINCAKEWien's Displacement Law
Stars behave approximately as black bodies: ideal objects that absorb all the radiation falling on them and emit a continuous spectrum of electromagnetic radiation that depends only on their temperature.
A graph of intensity against wavelength for a black body has a characteristic shape. It rises steeply to a peak at a wavelength λmax, then falls away more gradually at longer wavelengths.
