Phase difference in standing wave

Click For Summary

Discussion Overview

The discussion revolves around the concept of phase difference in standing waves, specifically addressing the conditions under which the phase difference is zero between two vibrating particles based on the number of nodes present between them. The scope includes theoretical explanations and conceptual clarifications.

Discussion Character

  • Conceptual clarification, Technical explanation

Main Points Raised

  • One participant inquires about the reasoning behind a zero phase difference when there is an equal number of nodes between two vibrating particles.
  • Another participant challenges the formulation of the question, suggesting that the term "equal" may be ambiguous and questioning the meaning of having an equal number of nodes between two particles.
  • A subsequent post clarifies the initial question by specifying that the intended meaning is an "even number of nodes" between the particles.
  • Another participant explains that the phase changes by Π (180 degrees) when passing one node, illustrating this with a description of the behavior of points on either side of a node in a wave snapshot.

Areas of Agreement / Disagreement

Participants do not reach a consensus on the initial question's formulation, and there is some clarification regarding the number of nodes. The explanation of phase change at nodes is presented without contestation, but the initial inquiry remains somewhat unresolved.

Contextual Notes

The discussion highlights potential ambiguities in terminology, particularly regarding the concept of "equal" nodes and the implications for phase difference. There is also an assumption that participants have a shared understanding of standing wave behavior.

Can someone explain why the phase difference is zero when the there is equal number of nodes between the two vibrating particles.

Thank you

You may need to reformulate. Between two particles can be some number of nodes. What would mean for this number to be "equal"?
Equality is a binary operator. Equal to what? Between two particles there is one number of nodes, not two.
 
Sorry, I meant to say even number of nodes
 
The phase changes by Π (180 degree) when you pass one node. You can see this if you imagine (or draw) a snapshot of the wave. On one side of the node all the points go up and on the other side they all go down.
