Light is a form of electromagnetic radiation that is visible to the human eye and is fundamental to various aspects of life on Earth. It behaves both as a wave and as a particle, a duality described by quantum mechanics. The spectrum of light includes not only visible light, which encompasses all the colors that can be seen with the human eye, but also extends to infrared and ultraviolet light, which, though invisible to us, have significant biological and technological functions. Light is essential for processes such as photosynthesis in plants, and it plays a crucial role in the regulation of biological rhythms. Additionally, light is a primary tool in technology and science, used in devices ranging from simple cameras to advanced medical imaging and in fields as diverse as communication, entertainment, and medicine.
