"Red Light" is a song written by Jonathan Singleton, Melissa Peirce and Dennis Matkosky, and recorded by American country music artist David Nail.
 It was released in February 2009 as the second single from his album "I'm About to Come Alive", and the third single of his career.
 It has become Nail's first Top 10 country hit on the U.S. "Billboard" Hot Country Songs chart.
 "Red Light" was Nail's highest-charting song on the Hot Country Songs chart for two years until "Let It Rain" went to number-one on January 21, 2012.
The Tyndall effect, also known as Willis-Tyndall scattering, is light scattering by particles in a colloid or else particles in a very fine suspension.
 It is named after the 19th-century physicist John Tyndall.
 It is similar to Rayleigh scattering, in that the intensity of the scattered light depends on the fourth power of the frequency, so blue light is scattered much more strongly than red light.
 An example in everyday life is the blue colour sometimes seen in the smoke emitted by motorcycles, in particular two-stroke machines where the burnt engine oil provides these
The term carotene (also carotin, from the Latin "carota", "carrot") is used for many related unsaturated hydrocarbon substances having the formula CH, which are synthesized by plants but in general cannot be made by animals (with the exception of some aphids and spider mites which acquired the synthesizing genes from fungi).
 Carotenes are photosynthetic pigments important for photosynthesis.
 Carotenes contain no oxygen atoms.
 They absorb ultraviolet, violet, and blue light and scatter orange or red light, and (in low concentrations) yellow light.

The "color" of the ocean is determined by the interactions of incident light with substances or particles present in the water.
 White light from the sun is made up of a combination of colors, which are broken apart by water droplets in a ‘rainbow’ spectrum.
 Large quantities of water, even in a swimming pool, would appear blue as well.
 When light hits the water surface, the different colors are absorbed, transmitted, scattered, or reflected in differing intensities by water molecules and other so-called optically-active constituents in suspension in the upper layer of the ocean.
 The reason open ocean waters often appear blue is due to the absorption and scattering of light.
 The blue wavelengths of light are scattered, similar to the scattering of blue light in the sky but absorption is a much larger factor than scattering for the clear ocean water.
 In water, absorption is strong in the red and weak in the blue, thus red light is absorbed quickly in the ocean leaving blue.
 Almost all sunlight that enters the ocean is absorbed, except very close to the coast.
 The red, yellow, and green wavelengths of sunlight are absorbed by water molecules in the ocean.
 When sunlight hits the ocean, some of the light is reflected back directly but most of it penetrates the ocean surface and interacts with the water molecules that it encounters.
 The red, orange, yellow, and green wavelengths of light are absorbed so that the remaining light we see is composed of the shorter wavelength blues and violets.
The Red Light District is the fourth studio album from Def Jam South recording artist Ludacris.
 The album was released on December 7, 2004 through Disturbing tha Peace and Def Jam Recordings, and was eventually certified double platinum by the RIAA.
 It debuted at number one on the "Billboard" 200 album chart with 322,000 copies sold in its first week.
 The album's title refers to a district in Amsterdam where prostitution is common; red-light district.
 The CD is accompanied by a 41-minute DVD made by Decon of the Ludacris visiting the Red Light District, a Cannabis growroom, an adult 'cam-house' and the recording of the Red Light District CD/DVD promo concert in Amsterdam.
Atmospheric optics deals with how the unique optical properties of the Earth's atmosphere cause a wide range of spectacular optical phenomena.
 The blue color of the sky is a direct result of Rayleigh scattering which redirects higher frequency (blue) sunlight back into the field of view of the observer.
 Because blue light is scattered more easily than red light, the sun takes on a reddish hue when it is observed through a thick atmosphere, as during a sunrise or sunset.
 Additional particulate matter in the sky can scatter different colors at different angles creating colorful glowing skies at dusk and dawn.
 Scattering off of ice crystals and other particles in the atmosphere are responsible for halos, afterglows, coronas, rays of sunlight, and sun dogs.
 The variation in these kinds of phenomena is due to different particle sizes and geometries.
The blue hour (from French "l'heure bleue ") is a period of twilight in the morning and in the evening, during the civil and nautical twilight phases, when the Sun is at a significant depth below the horizon and when the residual, indirect sunlight takes on a predominantly blue shade.
 On a clear day, blue hour can be a colorful spectacle, with the indirect sunlight tinting the sky yellow, orange, red, and blue.
 This effect is caused by the relative diffusibility of short blue wavelengths of light versus the longer red wavelengths.
 During the blue "hour" (typically a period about 20 minutes in length), red light passes straight into space while blue light is scattered in the atmosphere and therefore reaches the earth's surface.
 Many artists treasure this period because of the quality of the light.
 Although blue hour does not have an official definition, the blue color spectrum is most prominent when the sun is between 4° and 8° below the horizon.
