Visible light is what we can see with the human eye. It is a type of electromagnetic radiation (others include radio waves, infrared radiation, UV radiation) and is the portion of the electromagnetic spectrum that is made up of wavelengths of light, which range from about 390 nanometers (nm) to 700 nm.

Visible light is emitted by a variety of sources, including the sun, light bulbs, and screens, and is made up of a spectrum of colors, including red, orange, yellow, green, blue, indigo, and violet.
