👉 Light-particles, often referred to as photons or light quanta, are fundamental entities that make up electromagnetic radiation, including visible light, ultraviolet, and X-rays. These particles are characterized by their wave-particle duality, a concept central to quantum mechanics. On one hand, light behaves like a wave, exhibiting properties such as interference and diffraction. On the other hand, it displays particle-like behavior, such as the ability to transfer discrete amounts of energy in packets called photons. Each photon carries a specific amount of energy, determined by its frequency or wavelength, as described by Planck's equation \( E = h \nu \), where \( E \) is energy, \( h \) is Planck's constant, and \( \nu \) is the frequency. Light-particles are crucial in various phenomena, from the photoelectric effect, where photons eject electrons from a material, to the operation of lasers and fiber optics. Understanding light-particles is essential in fields like physics, chemistry, and engineering, as they underpin technologies ranging from solar cells to medical imaging.
