An Example of Doppler Effect

German Deutsche Version

An emergency ambulance with switched on siren passes a person standing at the street.

Note: This applet is not very realistic in one sense: As the Doppler effect should be seen as clearly as possible, the sound waves have a smaller velocity than in reality.
