An empty beaker. which is 32.0 cm tall: is open at the top and is used as a musical instrument in a band. The air in the beaker has a density of 1.25 lrgfm3 and a bulk modulus of 1.40 x 105 Pa. a. What is the speed of sound in the air inside the beaker? b. If you desire to have a fundamental frequency of 44D Hz how high from the bottom should the beaker be filled with water to produce this desired frequency? c. For the same water level as in part {b}: what frequency tuning fork will produce the next highest harmonic in the air column\"?I
