Medium

Real World Example

Have you ever tried to send a message across a crowded room by shouting, only to have your words get lost in the noise? This situation is similar to how a wave needs a medium to travel through and be heard, just like your voice requires air to carry it to the listener. In this analogy, the air is the medium that transports sound waves, much like the way your voice needs a clear path to reach the ears across the room, unaffected by other noises.
