An audio oscillator capable of producing notes of frequencies ranging from 500 Hz "to" 1500 Hz is placed constant tension T . The linear mass density of the wire is 0.75 g//m . It is observed that by varying the frequency of the oscillator over the given permissible rang the sonometer wire sets into vibration at frequencies 840 Hz and 1120 Hz . a. Find the tension in the string . b. What are the frequencies of the first and fourth overtone produced by the vibrating string?
