Light, visible light, or visible radiation is electromagnetic radiation that can be perceived by the human eye. 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.

3 days ago · light, electromagnetic radiation that can be detected by the human eye. Electromagnetic radiation occurs over an extremely wide range of wavelengths, from gamma rays with wavelengths less than about 1 × 10 −11 metre to radio waves measured in metres.
Light is a transverse, electromagnetic wave that can be seen by the typical human. The wave nature of light was first illustrated through experiments on diffraction and interference. Like all electromagnetic waves, light can travel through a vacuum. The transverse nature of light can be demonstrated through polarization.
Light: Science and Applications is an open access journal that publishes the highest quality articles in basic and applied optics and photonics.
light, That portion of the electromagnetic spectrum visible to the human eye. It ranges from the red end to the violet end of the spectrum, with wavelengths from 700 to 400 nanometres and frequencies from 4.3 × 10 14 to 7.5 × 10 14 Hz.
Higher energy light such as gamma rays, X-rays, and high energy UV light cause ionizations. They transfer enough energy to electrons so they can escape from the pull of the atom’s nucleus and turn the atom into an ion. Low energy UV and visible light cause electron transitions.
