ROYGBIV (in reverse VIBGYOR) is commonly used to remember the order of colors in the visible light spectrum, as seen in a rainbow. Richard of York gave battle in vain" (red, orange, yellow, green, blue, indigo, violet). Additionally, the fictitious name Roy G. Biv can be used as well. (red, orange, yellow, green, blue, indigo, violet).
This collection is divided into three sections: Sunfall (stories from Cherryh's Sunfall collection plus a new story, "MasKs"), Visible Light (stories from Cherryh's Visible Light collection) and Other Stories (stories from other collections and magazines). The story titles, showing where and when they were originally published, follow.
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 .
The optical atmospheric window is the optical portion of the electromagnetic spectrum that passes through the Earth's atmosphere, excluding its infrared part; [10] although, as mentioned before, the optical spectrum also includes the IR spectrum and thus the optical window could include the infrared window (8 – 14 μm), the latter is ...
Visible-light spectroscopy is an important tool in astronomy (as is spectroscopy at other wavelengths), where scientists use it to analyze the properties of distant objects. Chemical elements and small molecules can be detected in astronomical objects by observing emission lines and absorption lines.
In the original spectroscope design in the early 19th century, light entered a slit and a collimating lens transformed the light into a thin beam of parallel rays. The light then passed through a prism (in hand-held spectroscopes, usually an Amici prism ) that refracted the beam into a spectrum because different wavelengths were refracted ...

Articles relating to the visible spectrum, the portion of the electromagnetic spectrum that is visible to the human eye. Electromagnetic radiation in this range of wavelengths is called visible light or simply light. A typical human eye will respond to wavelengths from about 380 to 740 nanometers.
