👉 Light, often referred to as light particles or photons, is a form of electromagnetic radiation that travels through space at an incredibly fast speed. These particles are fundamentally different from matter particles like electrons and protons because they do not have mass and do not interact with each other via the strong nuclear force. Instead, light's behavior is primarily governed by the principles of quantum mechanics and electromagnetism. The term "light particles" emphasizes their discrete nature—photons come in specific energy packets, or quanta, which can be absorbed or emitted by atoms and molecules, leading to phenomena such as the photoelectric effect and the emission spectra of elements. This particle-like behavior of light contrasts sharply with its wave-like properties, as demonstrated by experiments like the double-slit experiment, showcasing its dual nature. Thus, understanding light as both particles and waves is crucial for explaining a wide range of physical phenomena, from the operation of solar panels to the workings of lasers and optical fibers.
