The primary wavelenght of radiation emitted by earths surface are?
The primary wavelength of radiation emitted by Earth's surface is in the thermal infrared range, typically around 10 micrometers (μm). This is known as long-wave radiation, which the Earth emits as heat energy.
Are the radiation wavelengths emitted by the sun longer than those emitted by the earth?
No, the radiation wavelengths emitted by the sun are shorter than those emitted by the Earth. The sun emits mostly visible light and shorter wavelength ultraviolet radiation, while the Earth emits longer wavelength infrared radiation due to its lower temperature.
How does long wavelength radiation contribute to the greenhouse effect?
Long wavelength radiation, such as infrared radiation, is emitted by Earth's surface after absorbing solar radiation. Greenhouse gases in the atmosphere trap this long wavelength radiation, leading to a warming effect known as the greenhouse effect. This process helps regulate Earth's temperature by keeping the planet warm enough to support life.
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.
Which greenhouse gas is the most powerful absorber radiation emitted by earth?
Carbon dioxide (CO2) is the most powerful absorber of longwave radiation emitted by Earth, leading to the greenhouse effect and global warming.
