write the short note on sun's radiation​

Answer 1

✾ΔŇŞŴ€Ř✾

➛Solar radiation is radiant energy emitted by the sun from a nuclear fusion reaction that creates electromagnetic energy. About half of the radiation is in the visible short-wave part of the electromagnetic spectrum. The other half is mostly in the near-infrared part, with some in the ultraviolet part of the spectrum.

Answer 2

Answer:

Hii user....

Good evening.....

Here is your answer.....

We feel hot when we stand out in the sun or when we are near a fire place. How

does the heat of the sun, or the fire place, reach us?The heat of the sun does not reach us either by conduction or by convection. This is because there is (mostly) empty space (vacuum) between the sun and

the earth. Conduction and convection, both require a material.medium for thetransfer of heat.It follows then that, there must be a third method of heat transfer. We call this

method of heat transfer as radiation. It may be defined as a method of heat transfer in which no material medium is required.
