An open cylindrical PVC tube of length 0.95 m is inserted into a tall measuring cylinder of length 0.90 m which is filled with water. The PVC tube is gradually lifted out of the water; at the same time a tuning fork is struck over the top of the PVC tube. (You have to Upload solution for this Question )
(*Ignore end correction)
When the top of the tube is 22.1 c m above the water level, the air column resonates with the tuning fork.
(a) What is the frequency of the tuning fork?
The PVC tube is lifted further out of the measuring cylinder until a second resonance occurs.
(b) Find the height above the water level at which this resonance occurs.
