Visible spectrum - Wikipedia
Electromagnetic radiation in this range of wavelengths is called visible light (or simply light). The optical spectrum is sometimes considered to be the same as the visible spectrum, but some authors define the term more broadly, to include the ultraviolet and infrared parts of the electromagnetic spectrum as well, known collectively as optical ...

可见光遥感 （visible spectral remote sensing）是指传感器工作波段限于可见光波段范围（0.78～0.4微米）之间的遥感技术 [6]。 电磁波谱的可见光区范围约在0.78～0.4微米之间，是传统 航空摄影侦察 和航空摄影测绘中最常用的工作波段。 因感光胶片的感色范围正好在这个频率范围，故可得到具有很高 地面分辨率 和判读与 地图制图 性能的黑白全色或彩色影像。 但因受太阳光照条件的极大限制，加之 红外摄影 和 多波段遥感 的相继出现，可见光遥感已把工作波段外延至 …
Visible Light Spectrum Overview and Chart - ThoughtCo
2024年5月2日 · The visible light spectrum is the section of the electromagnetic radiation spectrum that is visible to the human eye. Essentially, that equates to the colors the human eye can see. It ranges in wavelength from approximately 400 nanometers (4 x 10 -7 m, which is violet) to 700 nm (7 x 10 -7 m, which is red).

2021年1月16日 · The visible light spectrum is the region of the electromagnetic spectrum that human eyes see. It runs from wavelength of about 400 nanometers (nm) at the violet end of the spectrum to around 700 nm at the red end of the spectrum.
Visible Light Definition and Wavelengths - ThoughtCo
2020年1月9日 · Visible light is the part of the electromagnetic spectrum perceived by the human eye. Sometimes it is simply called "light." The approximate range of visible light is between infrared and ultraviolet, which is 380-750 nm or 430-750 THz. However, age and other factors can affect this range, as some people can see infrared and ultraviolet light.
The Visible Spectrum: Wavelengths and Colors - ThoughtCo
2024年6月7日 · The human eye sees color wavelengths ranging roughly from 400 nanometers (violet) to 700 nanometers (red). Light from 400–700 nanometers (nm) is called visible light or the visible spectrum, because humans can see it. Light outside of this range may be visible to other organisms but cannot be perceived by the human eye.
