👉 Light particles, often referred to as photons or light quanta, are fundamental particles that make up electromagnetic radiation, including visible light, ultraviolet, and X-rays. Unlike matter particles like electrons or protons, light particles do not have mass and travel at the speed of light in a vacuum. They are the primary carriers of electromagnetic energy and play a crucial role in various phenomena, from the colors we see to the functioning of solar panels and fiber optics. Light particles interact with matter through processes such as absorption, reflection, refraction, and scattering, which are essential for understanding optical behavior and applications in physics, astronomy, and technology.
