VISIBLE LIGHT The portion of the electromagnetic spectrum that can be detected by the human eye. It travels at the same speed as all other radiation, that is at 186,000 mile per second.
VISIBLE LIGHT - The light portion of the electomagnetic energy frequencies ranging from red to violet. It lies between the infrared and untraviolet invisible radiations.

LINE ECHO WAVE PATTERN (LEWP)
A wave-shaped bulge in a line of thunderstorms. It may often be seen as a "S"-shaped radar echo signature and is often associated with severe weather.
One way a picture can be taken is as a visible shot, that is best during times of visible light (daylight). Another way is as an IR (infrared) shot, that reveals cloud temperatures and can be used day or night.
RainbowA luminous arc featuring all colors of the visible light spectrum (red, orange, yellow, green, blue, indigo, and violet). It is created by refraction, total reflection, and the dispersion of light.
ultraviolet radiationAn electromagnetic radiation with wave-lengths longer than X-rays but shorter than visible light.Unmanned Aerospace Vehicle (UAV) ProgramA U.S.
When the sun is high in the sky, it generally appears white because all wavelengths of visible light reach an observer's eyes with almost equal intensity.
Rain and drizzle have drops much larger than the wavelength of visible light, so they will not show evident diffraction effects. They will, however, exhibit the rainbow and other reflection-refraction phenomena, as will ice crystals.
Visible light has wavelengths between 0.4 and 0.7 micrometers. Shorter wavelengths are known as the ultraviolet (UV) part of the spectrum, while longer wavelengths are grouped into the infrared portion of the spectrum.
The MSG has improved horizontal image resolution for the visible light spectral channel (1 km as opposed to 2.5 km on the current Meteosat) and all-digital data transmission which is 20 times faster (up to 3,2 Mbps) than on the current Meteosat.
rainbow: an arc displaying all colors in the visible light spectrum. Formed when light from the sun is reflected and refracted through water droplets. Always appears on the side of the sky opposite of the sun.
In order of decreasing energy, the principal forms of radiation are gamma rays, X-rays, UV (ultraviolet radiation). visible light, infrared radiation, microwaves, and radio waves.
LIGHT WAVES That part of the electromagnetic spectrum that contains visible light. The colors, from longest wave length to shortest, are red, orange, yellow, green, blue, indigo, and violet (ROY G. BIV). Related term: visible light ...
Electromagnetic radiation that has a wavelength shorter than visible light and longer than x-rays.
Infrared radiation- A form of energy with wave-lengths that are longer than visible light.
Ionosphere- The lower part of the thermosphere, where electrically charged particles called ions are found.
The portion of the spectrum that the human eye can detect is called visible light, between the longer infrared waves and the shorter ultraviolet waves.
Shortwave Radiation - in meteorology, radiation having a wavelength equal to or less than that of visible light
Shower - intermittent precipitation from a convective cloud, generally of short duration ...
The energy comes in many forms, such as visible light (that which we can see with our eyes). Other forms of radiation include radio waves, heat (infrared), ultraviolet waves, and x-rays.
The portion of the electromagnetic spectrum that has a very short wave length. It has a wavelength longer than gamma rays, yet shorter than visible light.
Infra-Red Radiation- Electromagnetic radiation of lower frequencies and longer wavelengths than visible light (greater than 0.7 microns (µ m)). Solar ultra-violet radiation is absorbed by the Earth's surface and re-emitted as infra-red radiation.
Mie scattering Produced by spherical particles having the same diameter as the wavelength of visible light; light is scattered equally at all wavelengths. ...
(1) the process by which radiated energy moves through space or material media; (2) energy propagated through space or through material media in the form of an advancing disturbance in electric and magnetic fields (e.g., visible light, x-rays, ...
