A light string is tied at one end to fixed support and to a heavy string of equal length L at the other end as shown in figure. Mass per unit length of the strings are `mu` and `9mu` and the tension is T. Find the possible values of frequencies such that point A is a node/ antinode.

`f/2, f, (3f)/2`…. Etc, when A is a node and `3/2f, 5/4 f, 7/4f`… etc, when A is an antinode, Here
`f = 1/L sqrt(T/mu)`

A heavy string is tied at one end to a movable support and to a light thread at the other end as shown in figure. The thread goes over a fixed pulley and supports a weight to produce a tension. The lowest frequency with which the heavy string resonates is 120 Hz. If the movable support is pushed to the right by 10 cm so that the joint is placed on the pulley, what will be the minimum frequency at which the heavy string can resonate ? .
