Doppler+Effect

The Doppler Effect

As shown in this picture, the airplane is moving toward the person, so the sound waves in the front of the plane are smashed together, making the sound of the plane have a higher pitch. In the back of the plane, the waves are spread apart, making the sound of the plane have a lower sound, when the plane is past the person.



In this picture, each sound wave that the plane makes is in front of the one before it. This makes the plane faster then the speed of sound. media type="file" key="sound doppler.mov" As seen here the jeep is traveling past a stationary object, the sound before the jeep past is a higher sound then the lower sound when the jeep pasted.
