Noun1.long wave- a radio wave with a wavelength longer than a kilometer (a frequency below 300 kilohertz) radio emission,radio radiation,radio wave- an electromagnetic wave with a wavelength between 0.5 cm to 30,000 m Based on WordNet 3.0, Farlex clipart collection. © 2003-2012 Princeton...
The lower the application temperature, the longer the wavelength (spectral response) of the instrument (pyrometer/scanner/imager) is – and vice versa. The below diagram shows typical temperature ranges covered by different spectral responses of infrared radiation temperature measurement devices. To ...
Light of the wavelength which is longer than the wavelength where it dopes in SiPROBLEM TO BE SOLVED: To provide a semiconductor control circuit element which can control an electric circuit at a high speed, by quickly and remarkably changing only a part of the resistance of the element ...

aUVA due to its longer wavelength has high penetrating power and reaches deep into the epidermis and demids of the skin 그것의 긴 파장 때문에 UVA에는 높은 투과능이 있고 피부의 표피 그리고 demids로 깊은 곳에서 도달한다[trans...
4、These admit heat, in the form of sunlight, but block its radiation back into space, in the form of longer-wavelengthinfra-red. infra-red:a type of light that feels warm but cannot be seen红外线的 •Their pilots are guided by an infrared optical system that shows images clearly even...
1找人帮我翻译!Wavelength determines the color of light.Violet light has the shortest wavelength.A sunrise or sunset is red because all the light has to penetrate our earth’s atmosphere when the sun is low on the horizon. The shorter wavelengths on the blue end tend to be absorbed or scat...
a. The sound wave has a longer wavelength and has the slower speed. b. The light wave has a shorter wavelength and has the slower speed. c. The light wave has a What is the speed of a wave with a wavelength of 3 m and a frequency of 0.1 Hz? If there is a cellphone ...
(Fig.5a). These noritic-composition materials dominated by orthopyroxene could represent ejecta materials delivered to region B by surrounding impact craters or, alternatively, the surface unit and/or materials characteristic of region B. Combining the longer wavelength absorption features and an ...
