Question

[04.01] which best describes the difference between radiation and conduction?

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.

Answer 2

in radiation, we don't need medium to conduct heat or energy but in conduction we need medium to conduct energy or heat ! conduction is done by contact as in radiation there is no contact !

for example or any info, comment !
