Three diffrent frequency cause occurance of beat

  1. Aug 4, 2014 #1
    1. The problem statement, all variables and given/known data



    2. Relevant equations



    3. The attempt at a solution

    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?
