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.

It gets louder and then gets quieter
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.
When does an observer at the crossing hear the lowest frequency of the trains whistle?
The observer at the crossing hears the lowest frequency of the train’s whistle when the train is moving away from them. This is due to the Doppler effect, where the pitch of the sound decreases as the source moves away from the observer.
What type of scientis twould use a Doppler radar and why?
The Doppler radar used in weather forecasting measures the direction and speed, or velocity, of objects such as drops of precipitation. This is called the Doppler Effect and is used to determine whether movement in the atmosphere is horizontally toward or away from the radar, which aides in weather forecasting. The radar was named for J. Christian Doppler, an Austrian physicist, who was the first to articulate the reason an approaching train's whistle will sound higher than the whistle as the train moves away.
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.
