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...
The colors of visible light are called thevisible spectrum. The colors of the spectrum correspond to wavelength ranges. Sir Isaac Newton divided the spectrum into red, orange, yellow, green, blue, and violet. He later added indigo, but Newton's "indigo" was closer to modern "blue," while ...
What is the Wavelength of Visible Light? When electromagnetic radiation occurs within a particular section of the electromagnetic spectrum is known as light. Generally, the term light refers to visible light and it is visible to the human eye. Experimentally, the light speed is found in vacuum t...
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 ...
Learn the definition of the visible color spectrum. Review the visible spectrum and a chart of each color spectrum wavelength in order from low to...
The sample excited by ultraviolet -visible lightcan emit bright green light. 样品在自然光照射后持续发出明亮的绿光. 互联网 Red has the longest wavelength ofvisible light, and violet the shortest. 红色拥有最长的可见光的波长, 蓝紫色是最短的. ...
A wide variety of instruments exist for recording the intensity of light as a function of wavelength. In the visible and ultraviolet regions of the spectrum, these include dispersive spectrometers (based on gratings and prisms) and nondispersive spectrometers (usually interferometric in nature). A ...
D. visible light E. infrared rays F. microwaves G. radio waves electromagnetic spectrum n. The entire range of electromagnetic radiation, which includes, in order of increasing frequency and decreasing wavelength, radio waves, microwaves, infrared radiation, visible light, ultraviolet radiation, x-ray...
the mixture was then carefully poured into a Teflon mould and cured under visible light (452 nm wavelength, 15 mW cm−2) for a predetermined time. 2D patterning hydrogels were prepared by placing shadow-masks on the top of the corresponding moulds before irradiation or fixing the laser...
Finally, our data indicate that the cytotoxic effect of short-wavelength light is predominantly a direct effect of cell illumination; photo-induced changes in the cell culture media play only a minor role.Similar content being viewed by others Phototoxicity of low doses of light and influence of...
