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.
What happens to the sound of a train whistle as the train approaches and then passes?
This is known as the Doppler effect. As the train approaches you, the wavelength of the sound waves it emits are compressed, and therefore the whistle sounds higher. When the train is moving away, the wavelengths are extended, causing the whistle to sound lower. If the train were not moving at all, the pitch you would hear from the whistle would be somewhere between the high and low pitches you hear when the train is moving.Read more: http://wiki.answers.com/Why_is_the_pitch_of_a_train's_whistle_higher_as_the_train_approaches_and_loweras_it_moves_away#ixzz1DToTuS3j
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.
Why is the pitch of a train's whistle higher as the train approaches and loweras it moves away?
This is known as the Doppler effect. As the train approaches you, the wavelength of the sound waves it emits are compressed, and therefore the whistle sounds higher. When the train is moving away, the wavelengths are extended, causing the whistle to sound lower. If the train were not moving at all, the pitch you would hear from the whistle would be somewhere between the high and low pitches you hear when the train is moving.
What happens to the sound of a train whistle as a train approaches and passes you why?
The raising and lowering of the whistle's pitch due to the alteration in the relative speed of the whistle as it goes by you, described by two terms that can be discovered by reading your homework assignment.

A train approaches a railroad crossing blowing its whistle the entire time. When does an observer at the crossing hear the lowest frequency of the train and acirc and 128 and 153s whistle?
An observer at the railroad crossing hears the lowest frequency of the train's whistle when the train is at its closest point to the crossing, just as it passes by. This phenomenon is due to the Doppler effect, where the frequency of the sound waves increases as the train approaches and decreases as it moves away. Therefore, the lowest frequency is experienced right after the train has passed, as the sound waves are stretched out.
Imagine you are waiting for a train to pass at a railroad crossing. Will the train whistle have a higher pitch as he train approaches you or after it passes you y?
As the train approaches you, the whistle will have a higher pitch due to the Doppler effect, where sound waves are compressed as the source moves closer. Once the train passes and moves away, the pitch will drop as the sound waves are stretched out. This change in pitch is a common experience when observing moving objects that emit sound.
How A train approaches a railroad crossing blowing its whistle the entire time. When does an observer at the crossing hear the lowest frequency of the train and whistle?
An observer at the railroad crossing hears the lowest frequency of the train and whistle when the train is moving directly towards them and just as it passes by. This phenomenon occurs due to the Doppler effect, where the sound waves compress as the train approaches, resulting in a higher frequency. As the train moves away, the sound waves stretch, causing the frequency to drop. Therefore, the lowest frequency is perceived just as the train is closest to the observer.
Would you hear a change in pitch if you are on a moving train and the train whistle blows?
Yes, you would hear a change in pitch. As the train approaches you, the pitch of the whistle would sound higher because the sound waves are compressed. As the train moves away from you, the pitch would sound lower as the sound waves are stretched out. This is known as the Doppler effect.
What happens the sound of a train whistle as the train approaches and then passed you?
It gets louder and then gets quieter
