    The visible spectrum is the band of the electromagnetic spectrum that is visible to the human eye. ... In terms of frequency, ...

  3. Electromagnetic spectrum - Wikipedia

    en.wikipedia.org/wiki/Electromagnetic_spectrum

    In frequency (and thus energy), UV rays sit between the violet end of the visible spectrum and the X-ray range. The UV wavelength spectrum ranges from 399 nm to 10 nm and is divided into 3 sections: UVA, UVB, and UVC. UV is the lowest energy range energetic enough to ionize atoms, separating electrons from them, and thus causing chemical reactions.

  4. Light - Wikipedia

    en.wikipedia.org/wiki/Light

    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 .

  5. Electromagnetic radiation - Wikipedia

    en.wikipedia.org/wiki/Electromagnetic_radiation

    In order of increasing frequency and decreasing wavelength, the electromagnetic spectrum includes: radio waves, microwaves, infrared, visible light, ultraviolet, X-rays, and gamma rays. [ 3 ] [ 4 ] Electromagnetic waves are emitted by electrically charged particles undergoing acceleration , [ 5 ] [ 6 ] and these waves can subsequently interact ...

  6. Frequency - Wikipedia

    en.wikipedia.org/wiki/Frequency

    Visible light is an electromagnetic wave, consisting of oscillating electric and magnetic fields traveling through space. The frequency of the wave determines its color: 400 THz (4 × 10 14 Hz) is red light, 800 THz (8 × 10 14 Hz) is violet light, and between these (in the range 400–800 THz) are all the other colors of the visible spectrum.

  7. Category:Optical spectrum - Wikipedia

    en.wikipedia.org/wiki/Category:Optical_spectrum

    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 . In terms of frequency, this corresponds to a band in the vicinity of 430–770 THz .

  9. Visible light communication - Wikipedia

    en.wikipedia.org/wiki/Visible_light_communication

    Visible light is only a small portion of the electromagnetic spectrum. In telecommunications, visible light communication (VLC) is the use of visible light (light with a frequency of 400–800 THz/wavelength of 780–375 nm) as a transmission medium. VLC is a subset of optical wireless communications technologies.
