      • Light is a type of electromagnetic radiation that can be detected by the eye. It travels as a transverse wave. Unlike a sound waves, light waves do not need a medium to pass through, they can travel through a vacuum.

    Light is sometimes also known as visible light to contrast it from "ultraviolet light" and "infrared light". Other forms of electromagnetic radiation that are not visible to humans are sometimes also known informally as "light". Polychromatic light is described by many different frequencies.

    Light is electromagnetic radiation. A particular frequency of this radiation (around 390-700 nm) is visible to the human eye. Everything that we see around us is because of light. Light is a form of energy and like all energies, it is produced from a source. In Physics, these are called light sources.
