SOLAR SYSTEM

Detailed explanation-1: -Radiation is a heat transfer process that does not depend upon the contact between the heat source, as in case with conduction and convection that depends on the same interaction between the heat source and the heated material. The thermal radiation also called infrared radiation can transmit heat through empty space.

Detailed explanation-2: -Radiation is a method of heat transfer that does not rely upon any contact between the heat source and the heated object as is the case with conduction and convection. Heat can be transmitted through empty space by thermal radiation often called infrared radiation. This is a type electromagnetic radiation .

Detailed explanation-3: -Radiation is the transfer of heat energy through space by electromagnetic radiation. Most of the electromagnetic radiation that comes to the earth from the sun is invisible. Only a small portion comes as visible light.

Detailed explanation-4: -Radiation is the transfer of energy as electromagnetic waves. It does not need to directly touch anything or move particles as in conduction and convection.

Detailed explanation-5: -As, radiation is the mode of heat transfer in which heat is radiated or transmitted from one place to another in the form of rays or waves. It does not require any material medium. It takes place by electromagnetic radiation.

Detailed explanation-6: -Radiation is the transfer of heat by electromagnetic waves. In addition to the sun, light bulbs, irons, and toasters also transfer heat via radiation. Note that, unlike conduction or convection, heat transfer by radiation does not need any matter to help with the transfer.
