  2. Visible spectrum - Wikipedia

    en.wikipedia.org/wiki/Visible_spectrum

    The visible spectrum is the band 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).

  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. Spectral color - Wikipedia

    en.wikipedia.org/wiki/Spectral_color

    A rainbow is a decomposition of white light into all of the spectral colors. Laser beams are monochromatic light, thereby exhibiting spectral colors. A spectral color is a color that is evoked by monochromatic light, i.e. either a spectral line with a single wavelength or frequency of light in the visible spectrum, or a relatively narrow spectral band (e.g. lasers).

    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 .
