A string has a linear density of 7.1 x 10" kg/m and is under a tension of 320 N. The string is 1.7 m long, is fixed at both ends, and is vibrating in the standing wave pattern shown in the drawing. Determine the (a) speed, (b) wavelength, and (c) frequency of the traveling waves that make up the standing wave. (a) Number i Units (b) Number i Units (c) Number UnitsAtube with a cap on one end, but open at the other end, has a fundamental frequency of 133.4 Hz. The speed of sound is 343 m/s. (a) If the cap is removed, what is the new fundamental frequency of the tube? (b) How long is the tube? (a) Number n Units c (b) Number n Units
