Explaining Low Frequency and Longitudinal Waves in Fluids

Click For Summary

Discussion Overview

The discussion focuses on understanding the relationship between low frequency and pitch in sound waves, particularly in the context of fluids. It also touches on the nature of wave propagation in fluids, specifically addressing why only longitudinal waves are present in such mediums.

Discussion Character

  • Exploratory, Conceptual clarification, Debate/contested

Main Points Raised

  • One participant seeks clarification on why low frequency contributes to low pitch and why only longitudinal waves occur in fluids.
  • Another participant suggests that pitch and frequency are essentially the same concept, indicating a potential misunderstanding in the original question.
  • A different participant explains that low frequency sound waves result in low pitch due to the slower vibration of the eardrum, questioning if this aligns with the original inquiry.
  • A follow-up question is raised regarding the Doppler effect, specifically about the number of cases and formulas associated with it.

Areas of Agreement / Disagreement

Participants express varying levels of understanding regarding the relationship between pitch and frequency, with some clarifying concepts while others seek further explanation. The discussion on the Doppler effect introduces additional complexity, indicating that multiple views may exist on this topic.

Contextual Notes

There are unresolved assumptions regarding the definitions of pitch and frequency, as well as the specifics of the Doppler effect cases and formulas.

seeking help..please

why do low frequency contributes a low pitch?how?& why only longitudinal in fluids?can any1 please explain to me,tq please..:smile:

The first one, I'm not clear what you are asking: pitch and frequency are just two different words that mean the same thing.

For the second part, you don't get transverse waves because the only way air molecules interact that can produce waves is via pressure. They are not connected to each other, so if one slides past another, there is no force to bring it back to where it started.
 


A low frequency sound wave has a low "pitch", that is is sounds "low frequency" because our eardrum vibrates more slowly and we interpret that "speed"...Is that what you were asking??
 


yes,thanks a lot...can i ask a que...the doppler effect actually has 8 cases which involves relative motion between a source and observer..so generally they only have 3 formulas only m i right?
