sound is wavelengths, and wavelengths get compressed when coming to you (and stretched when going away). the closer the wavelengths, the higher the pitch!

Would you hear a change in pitch if you are moving on a train and the whistle blows?

Yes, you would hear a change in pitch as you move towards or away from the source of the sound. This is due to the Doppler effect, where the frequency of the sound waves changes as the distance between the source and the observer changes.


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.


Why would you hear a change in pitch if you are on a moving train and the train whistle blows?

You would hear a change in pitch because of the Doppler effect. As the train moves towards you, the sound waves are compressed, resulting in a higher pitch. As the train moves away, the sound waves are stretched, resulting in a lower pitch.


Is a policeman's whistle high pitch or low pitch?

A policeman's whistle is typically high-pitched in order to grab attention quickly and alert those nearby to take notice of an emergency or situation that requires assistance.


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 exactly is the Doppler effect?

The Doppler effect is the change in frequency of a sound wave. The Doppler effect causes a siren or engine to have a higher pitch when it is approaching than it does when it is receding.

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 causes pitch to change?

Every sound vibrates with a particular fundamental frequency. When you change the wavelength of a sound, you change the pitch of a sound.


A train is approaching you from a distance There is a passenger on the train Who hears the higher pitch?

you hear the higher pitch. The train is approaching you, and also emitting the sound waves, and then catching up to the sound waves it had already emitted. Thus decreasing the wavelength of the wave it emited. This causes an increase in frequency. And an increase in frequency means higher pitch.


How do you whistle without lips?

You do not even need your lips to whistle. They actually produce poorer quality pitches than if you don't use your lips. You use your tongue and arc it up/down to change the pitch of the whistle and push a tight hole of air through your teeth.


How do you write the sound a whistle makes?

The sound a whistle makes is often described as "whoo" or "wee" depending on the pitch and intensity of the sound.
