Find safety tips and resources … Light, visible light, or visible radiation is electromagnetic radiation that can be perceived by the human eye. [1][2] Visible light spans the visible spectrum and is usually defined as having wavelengths in the range of 400–700 nanometers (nm), corresponding to frequencies of 750–420 terahertz. In its simplest form, quantum theory describes light as consisting of discrete packets of energy, called photons. However, neither a classical wave model nor a classical particle model correctly describes light; light has a dual nature that is revealed only in quantum mechanics.

White light is made up of all the many colors of light added together. When white light shines through a prism, it splits up into different colors, becoming a spectrum. Due to its finite speed, sunlight takes 8 minutes and 10 to 27 seconds to reach Earth, depending on the time of year. [1] The speed of light is the speed of electromagnetic waves. Light travels at slower speed inside materials like glass or water; its highest speed is in a vacuum.
