What else can I help you with?
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.
What is another name for ultraviolet light?
Ultraviolet light is also known as UV light. Ultraviolet light is electromagnetic radiation wavelengths and is emitted in black lights, tanning lamps and sunlight.
Sunscreen is used to protect the skin from exposure to which type of solar radiation Visible X-rays Infrared Ultraviolet Microwaves?
Sunscreen is used to protect the skin from ultraviolet radiation emitted primarily by our sun. The ozone layer also protects us from ultraviolet rays, however the current problems with holes in the ozone layer makes wearing sunscreen almost essential if one is going to be outside for an extended period of time.
What do the phosphors inside fluorescent bulbs absorb to create a glow?
The phosphors in fluorescent bulbs absorb ultraviolet light, which is emitted by the bulb's mercury vapor when electricity is passed through it. The absorbed ultraviolet light is then re-emitted as visible light, creating the glow we see.
Does the intensity of infrared waves emitted by the Sun change as the wavelength of the ultraviolet waves increases?
Yes, as the wavelength of the ultraviolet waves increases, the intensity of the infrared waves emitted by the Sun tends to decrease. This is because different wavelengths of electromagnetic radiation are emitted at different intensities by the Sun based on its temperature and composition.
What is a form of oxygen that protects us from high-energy radiation emitted by the sun?
Ozone is a form of oxygen that protects us from high-energy radiation emitted by the sun. It is found in the Earth's stratosphere and absorbs the majority of ultraviolet (UV) radiation before it reaches the Earth's surface, helping to shield living organisms from its harmful effects.
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.
Which layer of the earth atmosphere protects the earth from dangerous ultraviolet raditions of the sun?
Dangerous Ultraviolet radiations are the ones emitted from sun. These are protected by ozone.
How does the radiation emitted from the sun differ from the radiation emitted by earth?
The Sun emits a broader spectrum of radiation, including visible light, ultraviolet rays, and infrared radiation, while Earth primarily emits infrared radiation due to its lower temperature. The Sun's radiation is much more intense and has higher energy compared to the radiation emitted by Earth.
What radiation is in fire?
Fire emits electromagnetic radiation, including infrared, visible light, and ultraviolet light. These forms of radiation are responsible for the heat and light emitted by flames.
Which layer of the skin is associated with protection from the ultraviolet light?
The epidermis layer of the skin is associated with protecting the body from ultraviolet light. It contains melanocytes that produce melanin, a pigment that absorbs UV radiation and helps to protect the skin from damage. UV exposure can lead to skin damage and increase the risk of skin cancer, so protecting the epidermis is important.
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 is another name for ultraviolet light?
Ultraviolet light is also known as UV light. Ultraviolet light is electromagnetic radiation wavelengths and is emitted in black lights, tanning lamps and sunlight.

What is the type of radiation which tans or burns human skin is called?
The type of radiation that tans or burns human skin is called ultraviolet (UV) radiation. UV radiation is emitted by the sun and can have both positive effects (tanning) and negative effects (burning) on the skin depending on the level of exposure.
