Doppler Effect: Speed Relative to Ground, Source, or Listener?

AI Thread Summary
The Doppler Effect formula requires the speeds of the listener (VL) and the source (Vs) to be relative to the air, not the ground or each other. If the air is stationary, then the speeds are considered relative to the air itself. This distinction is crucial for accurately applying the Doppler Effect in various scenarios. Understanding this relationship helps clarify how sound waves behave when the source or listener is in motion. Accurate application of the formula is essential for precise calculations in physics and engineering.

hi i just want to ask about the formula of Doppler Effect . The speeds of the listener VL and the source Vs are relative to the ground, source, or listener ?

If the air is stationary relative to the ground (no wind to worry about), then the speeds of the listener and source will be relative to the ground.
 
Neither. It is relative to the air.
 
Thread 'Question about pressure of a liquid'

Thread 'Question about pressure of a liquid'

I am looking at pressure in liquids and I am testing my idea. The vertical tube is 100m, the contraption is filled with water. The vertical tube is very thin(maybe 1mm^2 cross section). The area of the base is ~100m^2. Will he top half be launched in the air if suddenly it cracked?- assuming its light enough. I want to test my idea that if I had a thin long ruber tube that I lifted up, then the pressure at "red lines" will be high and that the $force = pressure * area$ would be massive...

Thread 'Why is the 3 body problem unsolvable? And what will happen if someone solves it?'

I feel it should be solvable we just need to find a perfect pattern, and there will be a general pattern since the forces acting are based on a single function, so..... you can't actually say it is unsolvable right? Cause imaging 3 bodies actually existed somwhere in this universe then nature isn't gonna wait till we predict it! And yea I have checked in many places that tiny changes cause large changes so it becomes chaos........ but still I just can't accept that it is impossible to solve...
