Which form of heat transfer occurs via electromagnetic waves?

Explanation:
Radiation is heat transfer through electromagnetic waves. It doesn’t need a medium to travel, so energy can move through empty space—like sunlight reaching the Earth. That’s why you feel warmth from a fire or a heater even when you’re not touching it. Conduction uses direct contact and molecular interactions, and convection relies on the movement of a fluid carrying energy, so they’re different mechanisms.
