👉 The video describes light particles, often referred to as photons, which are fundamental components of light. Photons are massless, point-like particles that carry energy and momentum. They are the quanta of electromagnetic radiation, meaning they are the smallest units of light that can exist independently. When light interacts with matter, these photons can be absorbed, reflected, or transmitted, depending on the properties of the material. This behavior is described by quantum mechanics, where photons exhibit both particle-like and wave-like properties. For instance, in phenomena like the photoelectric effect, light particles knock electrons out of metals, demonstrating their particle nature. Conversely, when light passes through a double-slit experiment, it creates interference patterns, showcasing its wave-like characteristics. Thus, light particles encapsulate both aspects of light, explaining how it can behave as both a wave and a stream of discrete energy units.
