electromagnetic spectrum The electromagnetic spectrum can be measured in frequencies or in wavelengths. This diagram measures wavelengths in meters, ranging from the longest wavelengths (radio waves) to the shortest (gamma rays). Visible light, which is a band of colors from red to violet, is the...
In the visible light spectrum, which color has the longest wavelength? A. Red B. Blue C. Green D. Violet 相关知识点: 试题来源: 解析 A。解析:在可见光光谱中,不同颜色的光波长不同。红色光的波长最长,约为620 - 750纳米。蓝色光的波长较短,绿色光波长处于中间,而紫色光波长最短。所以这题答案...
Humans see light at the lower end of the visible spectrum, having a longer wavelength, about 740 nm, as red; we perceive light in the middle of the spectrum as green; and see light at the upper end of the spectrum, with a wavelength of about 380 nm, as violet. All other colors ...

The visible spectrum refers to the portion of the electromagnetic spectrum ranging from approximately 380 nm to 780 nm, where light of different wavelengths is perceived as different colors by the human eye. AI generated definition based on: AZimuth, 1998 ...
Visible light represents only one range of wavelengths within the electromagnetic spectrum. The archaeological potential of other wavelengths, such as in the near infrared or thermal ranges, is still undergoing assessment, but it has already been demonstrated that such hyperspectral scanning has the pote...
