Learn about the wave nature, sources, speed, and characteristics of light. Explore the history, experiments, and applications of light in physics and biology.
Light, visible light, or visible radiation is electromagnetic radiation that can be perceived by the human eye. [1] Visible light spans the visible spectrum and is usually defined as having wavelengths in the range of 400–700 nanometres (nm), corresponding to frequencies of 750–420 terahertz.
Perhaps the easiest way to think of light is as a stream of particles, but quantum particles, which are unlike ones that we can see. And all quantum particles, whether they are photons, or matter particles such as electrons, have wave-like behaviour.
