Radiation occurs when energy is transferred by electromagnetic waves

Electromagnetic waves ARE radiation.

A wave always carries energy.

Thermal or Heat energy

Explanation:

There are three ways through which heat transfer, it include conduction, convection and radiation, so radiation is the type of heat transfer.

Electromagnetic waves are those waves which travel with the speed of light. These are generated as the result of vibration between magnetic and electric field and these fields transfer heat or thermal energy through a medium or across vacuum by the process of electromagnetic radiation.

energy can be converted from one form to another, but it cannot be created or destroyed in ordinary chemical or physical means. do not understand what you are asking but hope this

the answer is f1 and d2 because if you put equal force on those two points the beam would balance trust me on this
