Doppler effect changes frequency of sound waves from "summary" of Fundamentals of Physics, Volume 1 (Chapters 1 - 20) by David Halliday,Robert Resnick,Jearl Walker
The Doppler effect is a phenomenon that occurs when there is relative motion between a source of sound waves and an observer. When the source is moving toward the observer, the frequency of the sound waves appears to be higher than when the source is stationary. This is because as the source moves closer to the observer, the sound waves are compressed, causing the frequency to increase. Conversely, when the source is moving away from the observer, the frequency of the sound waves appears to be lower than when the source is stationary. This is because as the source moves away from the observer, the sound waves are stretched out, causing the frequency to decrease. The change in frequency is dependent on the speed of the source and the speed of sound in the medium through which the sound waves are traveling. The Doppler effect can also be observed when the observer is moving relative to a stationary source of sound. If the observer is moving toward the source, the frequency of the sound waves appears to be higher than if the observer is stationary. This is because the observer is moving into the compressed sound waves, which increases the frequency. On the other hand, if the observer is moving away from the source, the frequency of the sound waves appears to be lower than if the observer is stationary. This is because the observer is moving away from the stretched out sound waves, which decreases the frequency. The change in frequency is once again dependent on the speed of the observer and the speed of sound in the medium.- The Doppler effect causes a change in the frequency of sound waves when there is relative motion between a source of sound and an observer. This change in frequency is a result of the compression or stretching of the sound waves due to the motion of the source or the observer.
