The primary wavelengths of radiation emitted by Earth's surface are in the thermal infrared range between 8 and 14 micrometers. This radiation is also known as longwave radiation and is a key component of Earth's energy balance.
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.
Longwave radiation refers to infrared radiation emitted by the Earth's surface and atmosphere, which can be absorbed by greenhouse gases and contribute to warming the atmosphere. Shortwave radiation, such as sunlight, is absorbed by the Earth's surface and then re-emitted as longwave radiation. This difference in wavelengths affects how energy is distributed in the atmosphere, with longwave radiation playing a key role in the greenhouse effect and shortwave radiation driving the Earth's climate system.
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.
Solar energy is absorbed by Earth's surface when sunlight reaches it and is converted into heat. This heat is then emitted back into the atmosphere in the form of infrared radiation. Greenhouse gases in the atmosphere trap some of this radiation, resulting in the warming of the Earth's surface.
Solar radiation reaches the surface of the Earth through the process of electromagnetic radiation emitted by the Sun. This radiation travels through space and reaches Earth's atmosphere, where it penetrates and warms the surface of the planet. The atmosphere helps block harmful radiation while allowing sunlight to reach the surface.
The wavelengths of radiation emitted by Earth are primarily in the infrared spectrum, ranging from about 5 to 100 micrometers. This is known as terrestrial or thermal radiation, and it is a form of heat energy emitted by the Earth's surface and atmosphere.

they are longer than those emitted by the sun.
Most of the radiation that produces a black body spectrum is emitted from the surface of the object itself. This radiation is a result of thermal vibrations of the atoms and molecules on the object's surface, which generate a continuous spectrum of electromagnetic radiation across various wavelengths.
Earth emits radiation across a wide range of wavelengths, including infrared, visible light, and some ultraviolet. This radiation is primarily determined by the temperature of Earth's surface and atmosphere.
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.
The radiation emitted by Earth's surface has longer wavelengths compared to solar radiation. Earth emits long-wave radiation in the infrared range, while solar radiation consists of shorter-wave radiation in the visible and ultraviolet ranges.
Longwave radiation refers to infrared radiation emitted by the Earth's surface and atmosphere, which can be absorbed by greenhouse gases and contribute to warming the atmosphere.

Infrared radiation is the type of radiation that gets trapped on Earth's surface by the greenhouse effect. This radiation is emitted by the Earth's surface in response to the incoming solar radiation and is absorbed and re-emitted by greenhouse gases in the atmosphere, leading to the warming of the planet.
Heat rises from the surface of the earth in the form of infra-red radiation.
Not as ultraviolet; the radiation is emitted as infrared radiation.
The Earth emits terrestrial radiation constantly, but the amount of radiation emitted depends on the temperature of the Earth's surface. Warmer objects emit more radiation than cooler objects, so the Earth emits the most terrestrial radiation during the day when it is exposed to sunlight.
