. The answer is; A Shorter than that emitted by the earth
When the electromagnetic radiations from the sun hit the earth, they may be reflected back to space, absorbed by the earth, or scattered. These cause some energy to be lost from the radiation from the sun. The radiation emitted from the earth is therefore of lower energy. This means they have a larger wavelength and longer frequencies.
Answer: 500 nm
Explanation:
The spectrum of Sun closely resembles the spectrum of black-body radiation.
The Sun radiates energy mainly in three regions -Ultraviolet, visible and infrared.
The peak wavelength of the spectrum obtained from Sun is approximately 500 nm which lies in the visible region.
