1. Sketch the lowest possible resonance frequency in each of the following tubes. 2. Sketch the next highest frequency in each of the above cases. 3. If the velocity of sound in the tubes is 340 m/s, and each of the above tubes is 1.00 m long, find the resonance frequency in each case a), b) and c) in problems 1 and 2 above. 4. A tuning fork is set up near the end of an air-filled tube of variable length as shown. As the length of the air column is changed, we hear resonances as we match the length to the wavelength of the harmonics. By changing the tube length by 10.0 cm, we go from one harmonic to the next for this sound wave. (See Sample Problem 14-17 for a similar question.) = 4 -variable- > a) What is the wavelength in air of this sound? b) What is the frequency of the tuning fork? 0) Would closing the right-hand end of the tube change the measurement of 10.0 cm
