How Is Light Hot

When a light beam hits an object and is completely absorbed, most of its energy is turned into heat (some of its energy can be turned into electricity and some can be turned into chemical potential energy).

How do photons create heat?

Radiant heat, also known as thermal radiation, is the transfer of electromagnetic radiation which describes the heat exchange of energy by photons. … The photons emitted by these moving charged particles will travel at the speed of light until they hit another particle, which absorbs its energy as kinetic energy.

How is light created in the sun?

Deep in the sun’s fiery core, atoms fuse and create light. … That interaction is called fusion, and it naturally occurs when two atoms are heated and compressed so intensely that their nuclei merge into a new element.
