# How can I use Stefan Boltzmann law?

The Stefan Boltzmann law states for the wave length to intensify as temperature increases. $\sigma$ is basically denoted. If temperature of light increases, (since we all know light is a wave.) the wavelength intensify, that's why there are different types of light waves. when the temperature of any matter increases, the speed, or acceleration increases. (since we know matter is a wave, based on movement.)
