What happens the sound of a train whistle as the train approaches and then passed you?
It gets louder and then gets quieter
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.

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 is the pitch of a train's whistle higher as the train approaches and loweras it moves away?

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.
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.
What is a palindrome for sound from the whistle?
"toot" is a palindrome for sound from the whistle.
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.
What is sound of whistle called?
Onomatopoeia
How do you spell a Whistle sound?
We all heard a whistle before, but when you are writing something and you want to type or write a whistle sound, it gets you thinking. If I were writing it i would put, WHEWWW, or, PHEWWWWWW. NO A whistle sound makes the sound Whistle
How can I use a whistle to scare dogs away effectively?
To effectively scare dogs away using a whistle, blow the whistle loudly and sharply when the dog approaches. The high-pitched sound is unpleasant to dogs and can startle them, causing them to retreat. Repeat as needed until the dog leaves the area.
