WebAs an object gets hot, its atoms and molecules vibrate. As they vibrate, they release energy in the form of light. Cooler things release longer wavelengths (infrared, red or orange); the hotter the object the more different wavelengths are released, so that a very hot object is “white hot”. Light without heat is also possible.
