👉 Light, often perceived as a form of energy, can be understood through the lens of quantum mechanics by considering its particle-like properties known as photons or light particles. These particles are fundamental to our understanding of electromagnetic radiation and play a crucial role in various phenomena, from the colors we see to the functioning of technologies like fiber optics and solar panels. Unlike classical particles, light particles exhibit both wave-like and particle-like behaviors, a duality encapsulated by the concept of wave-particle duality. Each photon carries a specific amount of energy, proportional to its frequency, as described by Planck's equation (E = hν). This energy can be transferred to matter, causing processes like photoelectric emission or excitation of electrons in atoms. Light particles are essential in explaining phenomena such as the photoelectric effect, where they eject electrons from a material when light of sufficient energy shines on it, and they underpin technologies like lasers and LEDs. Understanding light particles is thus fundamental to both theoretical physics and practical applications in modern science and technology.
