Ultraviolet radiation is the portion of the electromagnetic spectrum extending from the violet end of visible light to the X-ray region.
Ultraviolet (UV) radiation lies between wavelengths of about 400 nanometres and 10 nanometres, corresponding to frequencies of 7.5 × 1014 Hz to 3 × 1016 Hz. Most UV rays from the Sun are absorbed by the Earth's ozone layer. UV has low penetrating power, so its effects on humans are limited to the skin. These effects include stimulation of production of vitamin D, sunburn, suntan, aging signs, and carcinogenic changes. UV radiation is also used to treat jaundice in newborns, to sterilize equipment, and to produce artificial light.
What else can I help you with?
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.
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.
Which country has ultraviolet radiation?
At present, Australia is said to receive high levels of ultraviolet radiation.
Is visible light a type of ultraviolet radiation?
No, it is a type of electromagnetic radiation, which ultraviolet is part of as well.
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.
Is Ultraviolet radiation more penetrating than x-radiation?
No.
What 'ultra' produces radiation?
ultraviolet produces radiation.
