A vibrating sonometer wire is in resonance with a tuning fork of frequency 150 Hz. If only one loop is formed on the wire and the length of one loop is 40 cm, then the velocity of transverse waves on the wire will be
(a) 120 m/s
(b) 240 m/s
(c) 90 m/s
(d) 60 m/s

Dear studentlength of the sonometer wire is L=40cm=.40m fundamental frequency f0=150Hz when the fundamental wave is produced we have λ/2=0.40m ⇒λ=0.80m wave speed v=f0λ ⇒v=150×0.80=120m/sOption (1) is correctRegards
