A. The wavelengths of red light are longer than those of blue light. B. A four-meter-long fish looks three meters long underwater. C. Much water will be taken in by the swimmer deep in the water. D. You will see a ghost if you go as deep as 6 to 9 meters into the sea. ...
The experimental lighting conditions contain 2 colour temperatures (400K/6000K), 2 illuminations (400 lux/700 lux), and 3 dominant wavelengths of blue light (420nm/460nm/480nm). Reading and tasks are executed in the experimental process, in which the participants' brainwave, heart rate ...

9.In infrared light, shorter wavelengths look blue, and longer wavelengths appear red. 红外光下,较短的波长会程现蓝色,而较长的波长则程现红色。 10.The thermal radiation of shorter wavelengths than the visible are called ultraviolet. 波长短于可见光的热辐射称紫外线. ...
(1997b) found broiler chickens were more active and aggressive in red light and were calmer in blue light. Given the importance of UVA as a component of avian visual feedback, the provision of these wavelengths could be considered a valuable form of environmental enrichment (EE), using the ...
In 1800 the astronomer Sir William Herschel discoveredinfrared lightwhen he was exploring the relationship between heat and light. Herschel used a prism to split a beam of sunlight into a rainbow of colors (red, orange, yellow, green, blue, indigo, and violet) and measured how hot a ...
Sunlight, solar radiation that is visible at Earth’s surface. The amount of sunlight is dependent on the extent of the daytime cloud cover. Some places on Earth receive more than 4,000 hours per year of sunlight, as in the Sahara; others receive less th
Different bulbs and colors of light -- usually in the blue-green part of the spectrum -- penetrate skin and help the body clear the excess bilirubin that causes the yellow skin coloration of jaundice.
Since red (R) and blue (B) LED light has different quantum efficiency and photoelectric conversion efficiency, mixed RB with different proportions of R and B results in varied energy consumption. In order to improve the energy use efficiency of the closed-type plant production systems, the effec...
