Answer:

In physics, electromagnetic radiation consists of waves of the electromagnetic field, propagating through space, carrying electromagnetic radiant energy. It includes radio waves, microwaves, infrared, light, ultraviolet, X-rays, and gamma rays. All of these waves form part of the electromagnetic spectrum.The electromagnetic spectrum is the range of frequencies of electromagnetic radiation and their respective wavelengths and photon energies.

2) solar constant, the total radiation energy received from the Sun per unit of time per unit of area on a theoretical surface perpendicular to the Sun's rays and at Earth's mean distance from the Sun. It is most accurately measured from satellites where atmospheric effects are absent.

3) The two main characteristics of insolation are: ... Only 51% of the insolation reaches the surface of the earth as out of remaining 49%, 35% of insolation is directly reflected back to the space by atmosphere and the rest 14% is absorbed by the ozone layer.

4) Temperature depends on the latitude of a place . -temperature decreases with the increase in latitude on either side of the equator due to spherical shape of the earth and its annual revolution around the sun.
