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.


Does the Doppler Effect explain why you hear a train whistle differently after it passes you than you do as it approaches you?

Yes, the Doppler Effect explains this phenomenon. As the train approaches, sound waves are compressed, leading to a higher frequency and a higher pitch. As the train passes, sound waves are stretched, resulting in a lower frequency and a lower pitch, which is why the whistle sounds different before and after the train passes.


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 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.


What energy is wasted when blowing a whistle?

When blowing a whistle, the energy that is wasted is primarily in the form of sound energy. As air is forced through the whistle, it vibrates and produces sound waves, which dissipate into the surrounding environment as noise. Some energy is also lost as heat due to friction and air resistance as the air passes through the whistle's chamber and creates turbulence. Overall, the majority of the energy input into blowing a whistle is converted into sound energy and dissipated into the surroundings.

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
