The Nature of Photons and Energy Depletion
Photons are packets of energy that move at the speed of light and can be generated through various processes, such as atomic de-excitation. When an electron in an atom drops to a lower energy level, it releases energy in the form of a photon, which travels in a random direction. Examples of this can be seen in everyday scenarios, like the glowing of an electric stove, where vibrating particles emit light as they heat up. The entire concept illustrates how energy transitions between forms, with photons crisscrossing the universe continually as stars undergo similar processes.
