(electromagnetic radiation) Electromagnetic radiation in the http://www.answers.com/topic/wavelength range 4-400 nanometers. The ultraviolet region begins at the short wavelength (violet) limit of visibility and extends to the wavelength of long x-rays. It is loosely divided into the near (400-300 nm), far (300-200 nm), and extreme (below 200 nm) http://www.answers.com/topic/ultraviolet regions (see illustration). In the extreme ultraviolet, strong absorption of the radiation by air requires the use of evacuated apparatus; hence this region is called the vacuum ultraviolet. Important phenomena associated with ultraviolet radiation include biological effects and applications, the generation of http://www.answers.com/topic/fluorescence, and chemical analysis through characteristic absorption or fluorescence. See alsohttp://www.answers.com/topic/ultraviolet-radiation-electromagnetism. p.s. why go through all the trouble to go to answers or wikianswers.com and look for this question and since it wasnt asked or answered you posted it and waited until it was answered when you couldve just went to answers.com and typed ultraviolet radiation, where do you think i got it from.
What else can I help you with?
Is ultraviolet radiation visible or invisible?
By definition, ultra-violet light is outside the visible spectrum of EM radiation. Thus it is defined as invisible.
Does earth emit ultraviolet radiation?
The Earth itself does not emit ultraviolet radiation. Ultraviolet radiation primarily comes from the sun, which emits different wavelengths of light including ultraviolet radiation. When the Earth is exposed to sunlight, it can absorb and reflect this ultraviolet radiation.
Definition of fluorescence?
The visible or invisible radiation emitted by certain substances as a result of incident radiation of a shorter wavelength such as X-rays or ultraviolet light.
What has greater energy between ultraviolet and infrared?
Ultraviolet radiation has greater energy than infrared radiation. Ultraviolet radiation has shorter wavelengths and higher frequencies, while infrared radiation has longer wavelengths and lower frequencies.
Is visible light a type of ultraviolet radiation?
No, it is a type of electromagnetic radiation, which ultraviolet is part of as well.
Which country has ultraviolet radiation?
At present, Australia is said to receive high levels of ultraviolet radiation.
Is ultraviolet radiation the energy emitted by earth?
No, ultraviolet radiation is not emitted by the Earth itself. Ultraviolet radiation comes from the sun and is a form of electromagnetic radiation with shorter wavelengths than visible light. Earth's atmosphere filters and absorbs some of the incoming ultraviolet radiation before it reaches the surface.
When earths surface is heated it radiates most of the energy back into the atmosphere as ultraviolet radiation?
Not as ultraviolet; the radiation is emitted as infrared radiation.
Why do you need some ultraviolet radiation?
Ultraviolet radiation can kill some microorganisms and has a role in the vitamin A synthesis.
What did the ozone layer that filters ultraviolet radiation originated from?
The ozone layer that filters ultraviolet radiation originated from
Can ultraviolet radiation be used in heat lamps?
No, ultraviolet radiation cannot be used directly in heat lamps because ultraviolet light does not generate heat. Heat lamps typically produce infrared radiation, which is what provides the warmth. Ultraviolet radiation is more commonly used for applications like sterilization or tanning.
What is wrong with ultraviolet light?
Ultraviolet radiation can be a cause of skin cancers.
