Question 6.1: You have a tube open at both ends and you partially submerge it in water. You hold a tuning fork with a frequency of 400 Hz over the tube. You then slowly raise the tube out of the water until the tuning fork gets fairly loud, indicating you have reached the first harmonic for the tube. If the speed of sound in the air in the room is about 337 m/s, then what would the effective length of the tube, L, be, in metres? HINT: While it is indicated that the tube is open at both ends, when you submerge it in water, it becomes closed at one end, so: L = v = fa V 4 = 4 2n-1 4 2(1)-1_v V 4f Question 6.1: You have a tube open at both ends and you partially submerge it in water.
