👉 Light particles, often referred to as photons, are fundamental components of electromagnetic radiation and are accurately described as massless, point-like entities with no rest mass. They travel at the speed of light in a vacuum and exhibit both wave-like and particle-like properties, a concept known as wave-particle duality. The accuracy in describing light particles lies in their precise characteristics: they have no mass, which means they do not experience inertia or gravitational effects; they always move in straight lines unless deflected by another force; and their energy is quantized, meaning they can only exist in discrete packets (quanta) proportional to their frequency. This dual nature and behavior are fundamental to quantum mechanics and have been extensively validated through experiments, such as the photoelectric effect and Compton scattering, demonstrating their accuracy in explaining phenomena at both microscopic and macroscopic scales.
