Question

In Cambridge checkpoint book in question 4 the energy was transferred by particle .How is the transferred of heat energy by radiation different?

Answer 1

the question can be answered as all other methods or ways to transfer energies require medium where as transferring the energy without taking any aid from medium can be achieved through radiations (no medium required). also it is quickest way to have energy transformation as it doesn't need medium . so there is no loss of energy all the way.. also it moves in the form of waves at the speed of light (specific waves)
