👉 Light, as a form of electromagnetic radiation, consists of particles known as photons. These particles, despite being massless and nearly traveling at the speed of light, exhibit both wave-like and particle-like properties, a duality that is central to quantum mechanics. When light interacts with matter, it can be absorbed, reflected, or transmitted, but its fundamental nature remains that of these discrete packets of energy, or photons. This particle aspect of light explains phenomena such as the photoelectric effect, where light can eject electrons from a material, and the quantization of energy in atomic transitions. Thus, understanding light as both a wave and a particle provides a comprehensive framework for explaining its behavior across various physical processes.
