Longer than those emitted by the sun


What best describes the primary wavelengths of radiation emitted by Earth's surface?

they are longer than those emitted by the sun.


Does the sun or earth emit light with higher energy?

Only the sun emits radiation in the wavelengths of visible light, which is considerably higher energy than infrared emitted by Earth.


What is difference between atomic spectrum and electromagnetic spectrum?

The difference is that in an atomic spectrum, only the radiation of certain wavelengths is emitted. In a continuous spectrum, radiation of all wavelengths is present.


Is ultraviolet radiation the energy emitted by earth?

no


What kind of radiation is emitted by earth?

Infrared (heat)


What is terrestrail radiation?

The radiant entergy emitted by Earth


The wavelengths of thermal infrared emitted by the Earth are?

The Earth emits thermal radiation of a much lower intensity in the infrared rather than visible region . The wavelength of infrared rays is around 10^-6 meter.


Are the radiation wavelengths emitted by the sun longer than those emitted by the earth?

The radiation emitted by the Earth peaks around 10 microns, whereas that from the sun peaks under 1 micron. This is why Earth's radiation is referred to as longwave and solar radiation as shortwave, commonly. All objects emit radiation because all objects have a temperature. In fact, using Wien's Law you can very simply calculate the wavelength, lambda, of maximum emission: lamda(max) = c/T where c is a constant (2897) and T is the temperature of the emitting surface in Kelvin.


How is the radiation emitted by the sun different from the radiation emitted by Earth?

Radiation emitted by the sun has a wide range of frequencies from infrared, to visible light, to ultra-violet. It even has small amounts of microwaves, X-rays, and gamma rays. All this comes from the intense energy created in the sun's core. Radiation from the Earth is mostly (or maybe entirely) infrared radiation. This energy is of longer wavelength (lower energy) and comes from the heat emitted from the Earth as it is heated by the energy from the sun.


How is the radiation emitted by the Sun the same as the radiation emitted by Earth?

Both the Sun and the Earth radiate in the infrared, the Earth being a re-emitter of energy that was received from the Sun in both infrared and ultraviolet. Most of the Sun's infrared radiation never reaches the Earth's surface, but is absorbed in the atmosphere.


How does the amount of radiation emitted by the earth differ from that emitted by the sun?

The amount of energy radiated by the Earth is substantiallyless than the amount radiated by the sun.Fortunately.


Is the atmosphere heated chiefly by radiation emitted by earth true or false?

true

From Secret Diamond: "Diamond fluorescence is the visible wavelengths emitted by diamond when excited by invisible radiation." You can read more about it, below.


When does the earth emit terrestrial radiation?

Terrestrial radiation refers to long-wave electromagnetic radiation in the form of heat emitted from the Earth's surface and atmosphere. The Earth emits terrestrial radiation all the time.


Which greenhouse gas is the most powerful absorber of radiation emitted by Earth?

water vapor


Is speed of radiation emitted by the earth faster than the sun's?

The Earth is warmed by solar energy. How is this energy transferred from the sun to the Earth?

By radiation: mainly in the infrared wavelengths.


What is the difference between continuous spectrum and atomic emission spectrum?

In atomic emission spectra, only radiation of certain wavelengths is emitted. The emission spectra is composed of discrete emission lines. In the continuous spectrum, radiation of all wavelengths is present, and there are no discrete lines or bands present.


Everyone is exposed to radiation on a continuing basis from?

Everyone is exposed to radiation on a continuing basis from the Sun. The energy emitted by our Sun is radiation. The atmosphere of the earth filters out most of the radiation.


What form is radiation emitted from the earth's surface back into the atmosphere?

Heat rises from the surface of the earth in the form of infra-red radiation.


How do wavelengths of ultraviolet radiation compare to microwave radiation?

All ultraviolet radiation has shorter wavelengths than any microwave.
