Question

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

Answer 1

Both the Earth and the Sun behave more or less like blackbodies.

This means that the type of light emitted depends on the temperature, and the amount emitted depend on both temperature and size.

The sun is big and hot to emits a lot of energy per second, across all wavelengths, but with most of it in the form of visible light.

The earth is small and cool, so, while it still emits a broad range of wavelengths, the majority of photons are mid-infrared, and the smaller size combined with the lower temperature means that Earth emits a lot less energy per second in total

Answer 2

The sun emits the entire range of the spectrum from the electromagnetic spectrum, gamma to radio waves.

The earth basically emits heat, infrared. There is also some gamma from radioactive materials. Radiowaves are also being generated all over the earth.

Answer 3

The wavelength is different.  The sun's radiation is Ultraviolet (UV)...and the earth emits Infrared (IR) radiation.
