WebOct 11, 2016 · The sun’s radiation consists of small, massless packets of energy called photons. They travel seamlessly through space; … WebLight travels as a wave. But unlike sound waves or water waves, it does not need any matter or material to carry its energy along. This means that light can travel through a vacuum—a completely airless space. (Sound, on the other hand, must travel through a solid, a liquid, or a gas.) Nothing travels faster than light energy.
