What else can I help you with?
What happens to the sound of a train whistle as a train approaches and passes you?
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.

It's called a train whistle.

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.
What happens the sound of a train whistle as the train approaches and then passed you?
It gets louder and then gets quieter
A train passes by blowing its whistle As it passes the sound of the whistle is lower than it was on its way towards you This is due to?
a change in the sound's frequency caused by the motion of the sound's source
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.
Is train short or long sound?
A train can make both short sounds, like a whistle or horn, as well as long sounds, like the rumble of the train rolling along the tracks.
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.
How do you spell whistle?
That is the correct spelling of "whistle" (a sound or a noisemaker, or to make sound or music with the lips).
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.
