When a tuning fork is held over the open end of a very thin tube, as in the figure below, the smallest value of L that produces resonance is found to be 33.0 cm.

(a) What is the wavelength of the sound? [Hint: Assume that the displacement antinode is at the open end of the tube.]

(b) What is the next larger value of L that will produce resonance with the same tuning fork?
cm

(c) If the frequency of the tuning fork is 277 Hz, what is the speed of sound in the tube?
m/s
