Light is electromagnetic radiation, a form of energy that travels through space as oscillating electric and magnetic fields (and also as particles called photons). This distinguishes it from mechanical energy, which is tied to the motion or position of macroscopic objects, and from thermal energy, which relates to temperature and microscopic motion. The energy of light can be described by photons with energy E = hf, and it can be absorbed by matter to cause heating, but its fundamental nature is as electromagnetic radiation, not simply kinetic, thermal, or mechanical energy.
