Doppler Effect Science Adventure Box For School Project
Doppler Effect The Doppler effect causes the “neeeeeoowwm” sound of a speeding car passing by. When a sound source moves in relation to you, its pitch changes. From this effect you can determine whether the source is moving toward or away from you, and you can estimate how fast it’s going. HOW IT WORKS : When an oscillator (the buzzer) moves toward you, in effect, it is catching up slightly with its own sound waves. With each successive pulse of the buzzer, the sound source is a little closer to you. The result is that the waves are squeezed together, and more of them reach your ear each second than if the buzzer were standing still. Therefore, the pitch of the buzzer sounds higher. As the buzzer moves away from you, fewer waves reach your ear each second, so the resulting pitch sounds lower. The frequency of the buzzer itself does not change in either case. For your ears to detect this effect—called the Doppler effect—the sound source has to be moving toward or away from you at a minimum speed of about 15 to 20 mph (24 to 32 kph). As the source moves faster, the effect becomes more pronounced.
