Ultraviolet (UV) light is a type of electromagnetic radiation on the electromagnetic spectrum. The frequency of UV light is higher than that ofvisible light. This means it has more energy, which makes its wavelength shorter. This increased energy causes chemical effects in many objects — such a...

aCohen and Smith have shown that exposure to UV light can bleach this absorption band which probably produces the change in the index of refraction required for the grating formation . Cohen和史密斯表示,对紫外光的暴露可能漂白这吸收带宽哪些大概导致在为刺耳形成上需要的折射率的变化。 [translate] a...
Electromagnetic waves always move at the same speed in a vacuum, known as the speed of light. It equals 299,792,458 meters per second. Light Light is an electromagnetic wave, and as such has frequency and wavelength. Wavelength determines the light’s color, as described below. Wavelength ...
您的问题很简单。呵呵。百度知道很高兴帮助您解决您提出的问题。原句：Try the wavelength 365nm,20W uv light tube 翻译：试试波长365纳米,20 w紫外线光管 百度知道永远给您最专业的英语翻译。
WAVELENGTH CONVERSION OF EXCIMER-GENERATED UV LIGHTJeffrey I. LevatterMichael R. Stewart
Greater than 1.5 microW of tunable wavelength-modulated 308-nm radiation was generated by sum-frequency mixing of 90 mW of 835-nm diode-laser output and 1.5 W of 488-nm Ar(+)-laser output in a beta-barium metaborate crystal. Hydroxyl radicals formed in a discharge-flow reactor were detecte...
Wavelength and frequency of light are closely related. The higher the frequency, the shorter the wavelength. The lower the frequency, the longer the wavelength. The energy of a wave is directly proportional to its frequency but inversely proportional to its wavelength. That means the greater the ...
