To demonstrate standing waves, one end of a string is attached to a tuning fork with frequency 120 Hz. The other end of the string passes over a pulley and is connected to a suspended mass M, as shown.
The value of M is such that the standing wave pattern has eight loops “anti-nodes”. The length of the string from the tuning fork to the point where the string touches the top of the pulley is 1.1 m. The linear density of the string is 8×10−5 kg/m, and remains constant throughout the experiment.
Acceleration due to gravity is 9.8m/s^2

Determine the speed of the transverse wave along the string. Answer in units of m/s.

The speed of waves along the string in- creases with increasing tension in the string.
In order to double the number of loops in the standing wave pattern (so that there are 16 loops in total), how much suspended mass should we use? Answer in units of kg.

If a point on the string at an antinode travels a total distance of 9 cm during one complete cycle, what is the amplitude of the standing wave?
Answer in units of cm.
