Radiation

Real World Example

Imagine you're trying to get a message to a friend who doesn't have a phone or internet, so you decide to send a letter. Just like how the letter travels through the air without needing anyone to carry it directly to your friend, radiation involves energy traveling through space as electromagnetic waves without needing a medium like air or water. In both cases, whether it's your letter reaching your friend or energy moving from one place to another, the key is that there's no need for a middleman—be it a person carrying the letter or matter carrying the energy.
