What is light definition?

Light is a type of electromagnetic radiation that is visible to the human eye and travels in the form of waves. It is responsible for creating the sensation of sight in humans and other animals. Light can be produced naturally, through sources such as the sun or lightning, or artificially, through sources such as light bulbs or LED lights. It travels in straight lines and can be reflected, absorbed, or refracted by different materials or surfaces. Light is the basis of many technologies such as photography, fiber optics, and lasers.
