My Notes o Ask Your Teache 8 P.039 soln. calculate the length of a pipe that has a fundamental frequency of BB2 Hz. (Take the speed of sound in air to be 343 m/s.) (a) Assume the pipe is closed at one end. (b) Assume the pipe is open at both ends Need Help? My Notes o Ask Your reacher -la points serFSEo 18 P 044. A tuning fork with a frequency of f 532 Hz is placed near the top of the tube shown below. The water level is lowered so that the length L slowly increases from an initial value of 20.0 cm. Determine the next two values of L that correspond to
Explanation / Answer
(a) In a fundamental mode for a closed pipe, the length of the pipe is L = /4
Also =v/f, so L= v/4f = (343) / (4*882) = 0.097 m
(b) For an open pipe, L = /2
Also =v/f, so L= v/2f = (343) / (2*882) = 0.194 m
