The Doppler Effect is experienced in various situations, such as when a siren of an approaching ambulance seems to increase in pitch as it gets closer and then decreases as it moves away, or when the pitch of a passing car changes. It can also be observed with sound or light waves from moving sources, like stars or galaxies.
The wavelengths of the sound are compressed, making them shorter, and thus the frequency (and the pitch) higher. So the person in the oncoming car hears the siren operating at a higher pitch than the ambulance driver hears the same siren. This phenomenon is known as the Doppler effect.

Both are warnings of potential trouble.
