A sonometer wire, under a tension of 39 N, vibrates in unison with a tuning fork of
frequency 384 Hz. Find the beat frequency when the tension in the wire is reduced by 1N.

Solution
T =39 N , Frequency n =384 HzT' =  39 -1 = 38 NNew frequency  on increasing tension will be,n'=nT'Tn'=3843839n'=379 HzFrequency of beats will be,n'-n=379 Hz - 384 Hz  = 5 Hz
