photon interaction

Photon interaction refers to the ways in which photons, the basic units of light and electromagnetic radiation, engage with matter. When photons encounter particles, they can be absorbed, reflected, or transmitted. Absorption occurs when a photon is taken up by an atom or molecule, often causing it to gain energy. Reflection happens when photons bounce off surfaces, while transmission involves photons passing through materials. These interactions are fundamental to various processes, including photosynthesis in plants, vision in humans, and the functioning of technologies like solar panels and lasers.
