Does the velocity of sound change? I know pitch/frequency/wavelength changes.

Does the velocity of sound change? I know pitch/frequency/wavelength changes.

no, i dont believe the velocity changes in doppler effect calculations unless the sound is transferred to another medium or something

nope, velocity won't change.

ok thanks

nm, I don't think I understand this well enough to make such generalizations. see below.

velocity is a property of the medium

velocity is a property of the medium

absolute velocity is, yes. But when you walk toward a wave moving at the speed of sound, isn't the observed velocity increased? That is the basis for the Doppler equation, I think.

Well the velocity doesn't change. The fact that the doppler effect is concerned with a relative velocity doesn't change the fact that velocity itself is a property of the medium =)

If I remember correctly, there is a question from aamc8 asking about this. And the answer is velocity does not change.

yea, the relative velocity of the sound wave will be changed if you (the detector) are moving too. so if you are moving at 170m/s in the same direction as the wave which moves at 340m/s, it will be moving 170m/s relative to you. this is the doppler effect.

agreed.
