Name MVCC PHYSICS 150 Trade-and-Grade: Waves and Sound Grader's Name Tube Tuning Fork 2 4 A tuning fork vibrating at 512 Hz is held near one end of a tube of length L that is open at both ends, as shown above. The column of air in the tube resonates at its fundamental frequency. The speed of sound in air is 340 m/s. A. Calculate the length of the tube. B. The column of air in the tube is still resonating at its fundamental frequency. On the axes below, sketch a graph of the maximum speed of air molecules as the oscillate in the tube, as a function of position x, from x = 0 (left end) to x = L (right end of tube). Ignore random thermal motion of air molecules. Maximum Particle Speed L L/4 L/2 3L/4 C. The right end of the tube is now capped shut and the tube is placed in a chamber that is filled with another gas in which the speed of sound is 1005 m/s. Calculate the new fundamental frequency of the tube.
