An Example of Doppler Effect
( \newcommand{\kernel}{\mathrm{null}\,}\)
An emergency ambulance with switched on siren passes a person who is standing at the street.
W. Fendt 1998
Note: This app is not very realistic in one respect: As the Doppler effect should be seen as clearly as possible, the sound waves have a smaller velocity than in reality.
