A tuning fork is set up near the end of an air-filled tube of variable length as shown. By changing the length, various positions of maximum loudness (resonances) can be found. The difference in tube length between adjacent maxima is found to be 10.0 cm.

(a) What is the wavelength in air of this sound? 

(b) What is the frequency of the tuning fork (v=340m/s)? 

(c) Would closing the right-hand end of the tube change the 10.0 cm measurement?
