Question

Quizplus · Accepted Answer

The Doppler effect can be observed when an ambulance with a siren passes by. As the ambulance approaches the observer, the sound waves are compressed, resulting in a higher frequency and a higher pitch. As the ambulance moves away from the observer, the sound waves are stretched, resulting in a lower frequency and a lower pitch. This change in pitch is a good example of the Doppler effect.
