Question

is thermal energy being transferred from the metal pan to the eggs by radiation in this image? why or why not?

Explanation:

Thermal radiation is transfer of heat via electromagnetic waves. Here, eggs are in direct contact with pan. Conduction is heat transfer through direct contact. So, it's conduction, not radiation.

Answer:

No, thermal energy is not being transferred by radiation. Because the eggs are in direct contact with the pan, heat transfer is by conduction (direct contact), not radiation (which doesn’t need a medium and is via electromagnetic waves).
