Question 6: (16 points) You hold a tuning fork that plays at a a frequency f= 686hz above a 80cm long tube full of water. You slowly pour water out of the tube until you find a resonance. Recall the speed of sound is v=343. a) (5 points) How many centimeters of water do you need to pour out before you find the first resonance. That is how how long will the tube have to be in order for 686hz to be the natural frequency? Show your work. Be sure to include units.. 4L 480 #₂ = 343 m/s पर 680 = 343 4 (60-x) Just solve for L, that tells you 4L-680 343 m/s 2720 L = 343 2770 how mike air you need.-3. b) (11 points) How many times will the tuning fork cause a resonance with the tube as you pour water out? That is how many times will the water form a tube with 686hz as one of its harmonics? Show your work. Be sure to include units. 11
