Longwave & Shortwave Radiation extended definition

Everything that has a temperature gives off electromagnetic radiation (light).  The sun is extremely hot and has a lot of energy to give, so it gives off shortwave radiation because shortwave radiation contains higher amounts of energy  The earth is much cooler, but still emits radiation.  Earth’s radiation is emitted as longwave because longwave radiation contains a smaller amount of energy.
