it grows louder because the sound waves become more tightly compressed

The Doppler effect.


How does Sheldon explain the Doppler effect in "The Big Bang Theory"?

In "The Big Bang Theory," Sheldon explains the Doppler effect by using the example of a train whistle changing pitch as it approaches and then passes by. This change in pitch is due to the compression and expansion of sound waves as the train moves relative to the observer.


How can you use Doppler effect in a sentence?

Example sentence - We are learning to what the doppler effect is and how to use it.


How is the Doppler effect on light waves analogous to the apparent change in pich of a passing train whistle?

When the train gets close to you the sound wave are compressed making a higher pitch noise and as the train passes the sound waves become lengthened. That is the doppler effect in a nutshell. Now just compare it to how the doppler effect changes light waves.


Why dont you notice the Doppler effect for a slow moving train?

The Doppler effect occurs whether the sound source or the listener is moving. You wont notice the Doppler effect on a slow moving train because the radio wave is reflected, its frequency changes depending on the speed of the object.

Does the Doppler Effect mean that an observer ahead of a train hears the train at a higher frequency sound than an observer behind the train?

Yes that is the case.


Is an echo an example of the Doppler effect?

No, an echo is not an example of the Doppler effect. The Doppler effect occurs when there is a change in frequency of a wave due to the relative motion between the source of the wave and the observer. An echo is created when sound waves reflect off a surface and return to the listener, producing a repeated sound.


Is true of the Doppler effect?

What do you call an effect where in the pitch of the whistle rises as the train approaches the station and falls off as it moves away?

This effect is called the Doppler effect. It occurs when there is relative motion between the source of a sound (like a train whistle) and an observer. As the train approaches, the sound waves are compressed, resulting in a higher pitch, and as it moves away, the sound waves are stretched, causing a lower pitch.
