👉 Light particles, often referred to as photons, are fundamental components of electromagnetic radiation and are considered the smallest discrete units of light energy. These particles exhibit both wave-like and particle-like properties, a concept central to quantum mechanics. Photons carry energy and momentum, with their energy directly proportional to the frequency of the light they represent (E = hν, where E is energy, h is Planck's constant, and ν is frequency). While light can be described by waves in classical physics, its interaction with matter, such as absorption, emission, and scattering, is best explained through the particle model. This dual nature of light—both wave and particle—underpins many phenomena in optics, quantum mechanics, and astrophysics, from the behavior of atoms to the functioning of solar cells and lasers.
