a) A 2.00m long wire having a mass of 0.1kg is fixed at both ends. The tension of the wire is maintained at 20N. When the wire is vibrating the first node is observed at a point 0.40m form one end.
(i) In what mode is the wire vibrating? (i.e. fundamental, 10th harmonic etc.)
(ii) With what frequency is it vibrating?
Standing waves on a stretched string, to find the harmonics in which the string oscillates.
