How radiation from sun is different from that of earth?

Answer 1

Radiation emitted by the sun has a wide range of frequencies from infrared, to visible light, to ultra-violet. It even has small amounts of microwaves, X-rays, and gamma rays. All this comes from the intense energy created in the sun's core.

Radiation from the Earth is mostly (or maybe entirely) infrared radiation. This energy is of longer wavelength (lower energy) and comes from the heat emitted from the Earth as it is heated by the energy from the sun.

Answer 2

Both the Sun and the Earth radiate in the infrared, the Earth being a re-emitter of energy that was received from the Sun in both infrared and ultraviolet. Most of the Sun's infrared radiation never reaches the Earth's surface, but is absorbed in the atmosphere.

Answer 3

The Sun is about 20 times hotter than the Earth. That means that the average frequency of the radiation from the Sun is higher, and the total amount of power radiated per square meter is much higher.

Answer 4

The sun radiates somewhat more electromagnetic energy than the Earth does.
This is because the sun is bigger, and also because there is no nuclear fusion
going on inside the Earth.

Answer 5

The amount of energy radiated by the Earth is substantially
less than the amount radiated by the sun.

Fortunately.

Answer 6

They are both roughly spherical. They both have layered structures. They both have what may be considered atmospheres, though of very different kinds. They rotate.

Answer 7

Because chemical elements are the same.
