1. A tuning fork is sounded above a (narrow) resonating tube as in lab. The first resonant situation occurs when the water level is 0.08 m from the top of the tube, and the second when the level is at 0.24 m from the top. Let vsound = 340 m/s.
a) Where is the water level for the third resonant point?
b) What is the frequency of the tuning fork?
2. Find the first four harmonics of a hollow pipe 30 cm long, open at both ends. Let v_sound = 340 m/s.
3. A string is stretched between two supports separated by 1.2 m. Given that the speed of transverse waves on the string is 800 m/s, find the frequencies of the first three harmonics.
