The visible spectrum is 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 about 750 nanometers. In terms of frequency, this … See more In the 13th century, Roger Bacon theorized that rainbows were produced by a similar process to the passage of light through glass or crystal. In the 17th century, Isaac Newton discovered that … See more Many species can see light within frequencies outside the human "visible spectrum". Bees and many other insects can detect ultraviolet light, which helps them find See more Spectroscopy is the study of objects based on the spectrum of color they emit, absorb or reflect. 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. See more • High-energy visible light • Electromagnetic absorption by water See more Color displays (e.g. computer monitors and televisions) cannot reproduce all colors discernible by a human eye. Colors outside the color gamut of the device, such as most See more Heat Although non-visible infrared light is more commonly thought of as "heat radiation", any frequency of light, including visible light, will heat … See more WebMay 10, 2024 · The most common optical bands are R (red), V (visible), and B (blue), but astronomers also use I (infrared) and U (ultraviolet). Because radio wavelengths are so much longer than visible ones, the color bands we use for radio are often defined differently.
