👉 Light particles, often referred to as photons or elementary light quanta, are fundamental entities that exhibit both wave-like and particle-like properties. In the context of quantum mechanics, these particles are required to interact with matter and energy in discrete packets, or quanta, rather than continuously. This requirement is rooted in the principle of quantization, which posits that certain physical phenomena, such as the emission and absorption of light, can only occur in specific, indivisible amounts. These light particles must adhere to specific energy levels, described by Planck's equation (E = hν), where E is the energy of the photon, h is Planck's constant, and ν is the frequency of the light. Understanding this requirement is crucial for explaining phenomena like the photoelectric effect, where light can eject electrons from a material only if its photons have sufficient energy, and for the behavior of light in various media, including absorption, reflection, and refraction.
