WebNov 1, 2013 · There is no simple direct explanation of how photon energy is transformed into heat. One can argue for visible light that an electron can absorb a photon and radiate it without increasing kinetic energy of atoms (no increase oh heat). That is true but that is a very simplistic picture of what happens in reality. WebThe chemical energy is directly converted into light energy in a combustion process or upon some chemical reaction caused coming in contact with the air called an oxidation reaction. Or, chemical energy can also be converted to electrical energy to obtain light energy. The mobility of the charges present in the objects also produces electrical ...

WebNov 17, 2024 · Nearly all thermal energy on Earth originates from the sun and radiates to the surface of our planet, traveling in the form of electromagnetic waves, such as visible light. Materials on Earth then absorb these waves to be used for energy or reflect them back into space. In an energy transformation, energy changes form. WebNov 24, 2016 · The simplest answer is that the filament heats up and gets so hot that it glows. As to how it heats up; the electric field forces electrons to rush around the circuit. They encounter a lot of resistance in the filament and it is this "friction" that leads to heating.
