Sound wave propagation and doppler shift wrt the medium

AI Thread Summary
Sound wave propagation and Doppler shift are influenced by the medium, as demonstrated in a scenario where two people match pitch while facing each other. In still air, both individuals perceive the sound at the same frequency. However, when wind is introduced, the person downwind would hear the sound sooner and at a higher pitch due to the wind aiding the sound wave's travel. The discussion highlights the importance of the medium's motion in altering sound perception. Ultimately, the interaction between sound waves and the medium significantly affects how frequencies are experienced by observers.

In contemplation and research regarding another thread's question about the asymmetry of doppler shift wrt the medium, I find myself trying to imagine two people talking... or perhaps better yet matching pitch. In still air with both people facing each other at ten paces of course they would agree that both are right on key.

If the wind were to blow the person downwind would hear the tone sooner or later than the person upwind and higher or lower pitch?

Hi there :smile:

what tone? and where is it placed relative to the 2 people ? and what is the actual direction of the wind
You never mentioned any tone source in your initial scenario

draw a pic with people and tone source positions and wind direction

Hi and thanks in advance...

I am inclined to believe the sound waves would travel faster with the motion of the medium increasing the frequency heard downwind?
 

Thread '1:1 versus 2:1 Mechanical Advantage debate'

The rope is tied into the person (the load of 200 pounds) and the rope goes up from the person to a fixed pulley and back down to his hands. He hauls the rope to suspend himself in the air. What is the mechanical advantage of the system? The person will indeed only have to lift half of his body weight (roughly 100 pounds) because he now lessened the load by that same amount. This APPEARS to be a 2:1 because he can hold himself with half the force, but my question is: is that mechanical...

Thread 'Newton's first law?'

Some physics textbook writer told me that Newton's first law applies only on bodies that feel no interactions at all. He said that if a body is on rest or moves in constant velocity, there is no external force acting on it. But I have heard another form of the law that says the net force acting on a body must be zero. This means there is interactions involved after all. So which one is correct?

Thread 'Beam on an inclined plane'

Thread 'Beam on an inclined plane'

Hello! I have a question regarding a beam on an inclined plane. I was considering a beam resting on two supports attached to an inclined plane. I was almost sure that the lower support must be more loaded. My imagination about this problem is shown in the picture below. Here is how I wrote the condition of equilibrium forces: $$ \begin{cases} F_{g\parallel}=F_{t1}+F_{t2}, \\ F_{g\perp}=F_{r1}+F_{r2} \end{cases}. $$ On the other hand...
