Yes, light is a physical phenomenon. It is a form of electromagnetic radiation, which is a fundamental force of nature. Light consists of particles called photons that exhibit properties of both waves and particles. It can be produced by various sources, such as the Sun, stars, light bulbs, or lasers. When light interacts with matter, it can be reflected, refracted, absorbed, or transmitted, depending on the properties of the material it encounters. The study of light and its behavior is a branch of physics known as optics.
