What is a good way to demonstrate the doppler effect?
A novel experiment to demonstrate doppler shifting A novel experiment to demonstrate doppler shifting There are many everyday examples of the Doppler effect – the changing pitch of police and ambulance sirens, train whistles and racing car engines as they pass by. In each case, there is an audible change in pitch as the source approaches and then passes an observer. The effect arises because sound waves arrive at the listener’s ear closer together as the source approaches, and further apart as the sound waves recede. The faster the object is moving, the greater the effect. To illustrate the Doppler shift and the effect that the distance to the source has on it, Jean-Pierre Lebreton performed the following simple experiment: A video camera recorded a scooter, blaring its horn, approaching and passing by the cameraman. Two recordings were made; the first one while the cameraman was standing close to the road on which the scooter was driving, the second one some distance away from the roa
