Question

How is radiation different from conduction and convection

Answer 1

Convection is the transfer of energy by movement of a medium, whereas radiation is the transfer of energy by, well, thermal radiation. Conduction also requires a medium, but, again, it is a fundamentally different mechanism than either convection or radiation; in this case it is the transfer of energy through a medium.

hope this helps!

Answer 2

Answer:

The answer is In radiation, energy can propagate in a vacuum.

Explanation:

Radiation, convection and conduction are forms of heat and energy transfer, but they differ in that the radiation phenomenon can propagate energy not only in material media but also in the form of electromagnetic waves or subatomic particles through vacuum, while convection and conduction can only be propagated by a material medium.
