Homework Help Overview

The discussion revolves around the frequencies of sound waves and the phenomenon of beats, specifically focusing on determining the frequency of sound source Y based on its interaction with sound sources X and Z. The problem involves understanding how beat frequencies relate to the original frequencies of the sources.

Discussion Character

  • Exploratory, Assumption checking

Approaches and Questions Raised

  • Participants discuss the possible frequencies for source Y based on the number of beats produced when sounded with source X. They explore the implications of beat frequencies and question how to resolve the ambiguity between two possible values for Y.

Discussion Status

The discussion is ongoing, with participants acknowledging the ambiguity in determining the frequency of Y. Some suggest that additional information comparing Y with Z could clarify the situation, but it appears that no further details are provided in the original question.

Contextual Notes

Participants note that the problem does not provide a second part to compare the frequencies of Y and Z, which contributes to the uncertainty in identifying the correct frequency for Y.

my ans is f Y = 260hz. but the ans is f Y= 252hz . am i wrong? why?
Since X is 256Hz., when sounded with Y 4 beats are produced, so Y is either sounding at 260 or 252Hz (+-4Hz).
When Z is sounded with X, 8 beats are heard, so Z is either 264 or 248Hz.(+-8Hz). my fZ is (264Hz.) now the f Y can be 260 or 252Hz (+-4Hz).
which one to choose?

Could be either 252 or 260.
Is there a second part that compares fY with fZ? That would resolve the ambiguity.

no . that's the whole question. so it can be bith 260hz and 252hz?
