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?

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

Could someone please help me out on this.Thank you! I need a good explanation on this please.
