Example:
Imagine you're trying to get someone's attention across a crowded room without being able to physically approach them. Just like you might wave your hands or use a flashlight to signal your presence from a distance, radiation transfers energy through electromagnetic waves without needing a medium like air or solid objects. In both cases, whether it's your signal reaching the other person or energy moving through electromagnetic waves, there's no need for direct contact or a physical intermediary—it's all about transmitting a message or energy across space.

Radiation: The transfer of energy by electromagnetic waves, it does not require matter. Radiation is energy traveling through space as waves or particles.
