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?

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.
Which wave property is related to how loud or soft a sound is?
The pitch is determined by the frequency of the wave.The absolute loudness is determined by the wave's amplitude.The loudness perceived by the ear is affected by both the above, because the sensitivity of the ear is frequency dependent.

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?
Since you are also on the moving train, the pitch should remain constant.
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.
What effect causes a siren to change in pitch as it passes by?
doppler effect
