releasing energy in the form of photons. The color of the light (corresponding to the energy of the photons) is determined by the energy required for...

to 30 eV in energy. Hence photobiology entertains some, but not all, of the UV spectrum. Biological effects of high-energy visible light Infrared Ultraviolet...

because their high photon energy is able to ionize atoms, causing chemical reactions. Longer-wavelength radiation such as visible light is nonionizing;...

reduction of light emanating from a nuclear detonation. Eventually, the shock wave dissipates to the point where the light becomes visible again giving...

physicists refer to light as electromagnetic radiation of all wavelengths, whether visible or not. High-energy visible light is blue-violet light with a higher...

deliberate use of light to achieve practical or aesthetic effects. Lighting includes the use of both artificial light sources like lamps and light fixtures...

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

1019 times the energy of a 101 Hz extremely low frequency radio wave photon. The effects of EMR upon chemical compounds and biological organisms depend...
