Q. In a sonometer wire, the produced waves an
Solution:
The simplest apparatus for demonstrating the vibrations of a stretched string is a sonometer. When a wire damped to rigid supports at its ends, is plucked in the middle transverse progressive waves travel towards each end of the wire.
By the superposition of the incident and the reflected waves, transverse stationary waves are set up in the wire. These waves are also polarised.
