Here, υA=258Hz,υB=262Hz
Let the frequency of unknown turning fork be υ.
It produces υb beats with A and 2υb with B. Therefore,
υA−υ=υb ......(i)
and υB−υ=2υb ......(ii)
Subtract (i) from (ii), we get
υB−υA=υb
Substituting the giving values, we get
262−258=υb
υb=4Hz
From (i), υ=υA−υb=(258−4)Hz=254Hz
