The Doppler Effect changes how we hear sounds when things are moving.
When something that makes noise gets closer to us, the sound waves get squished together. This makes the sound higher in pitch, like how an ambulance siren sounds sharper as it comes closer.
But when the sound source moves away from us, the waves are stretched out. This creates a lower pitch, like how the siren sounds deeper as it goes further away.
Think about watching a train as it goes by.
As the train comes closer, you hear a high-pitched whistle. But as it moves away, the sound gets lower.
This effect makes sounds more interesting and helps us understand how things are moving around us.
