The correct answer is: The earth’s radiation is often referred to as longwave radiation, while the sun’s radiation is often referred to as shortwave radiation.
Shortwave radiation is a type of electromagnetic radiation with a wavelength shorter than that of visible light. It is emitted by the sun and other hot objects. Shortwave radiation can be absorbed by the Earth’s atmosphere, causing it to warm.
Longwave radiation is a type of electromagnetic radiation with a wavelength longer than that of visible light. It is emitted by the Earth’s surface and other objects that have been warmed by the sun. Longwave radiation can be emitted back into space by the Earth’s atmosphere, or it can be absorbed by greenhouse gases, which trap heat and cause the Earth to warm.
The Earth’s radiation is often referred to as longwave radiation because it has a longer wavelength than the sun’s radiation. The sun’s radiation is often referred to as shortwave radiation because it has a shorter wavelength than the Earth’s radiation.
