PHYSICS 6B Ch.12 Worksheet www.clas.ucsb.edu/staff/vince/ 1) Sound waves travel in air with a speed of 343 m/s. The lowest frequency sound that the average person can hear is 20.0 Hz; the highest frequency is 20 kHz. Find the wavelengths corresponding to these frequencies. 2) A 12-m rope is pulled tight with a tension of 92N. When one end of the rope is given a “thunk” (disturbed from its equilibrium position) it takes 0.45s for the disturbance to propagate to the other end. What is the mass of the rope? 3) One of the harmonics on a string 1.3m long has a frequency of 15.6 Hz. the next higher harmonic has a frequency of 23.4 Hz. Find (a) the fundamental frequency, and (b) the speed of the waves on this string. 4) A guitar string 62 cm in length vibrates with a standing wave that has three antinodes. a) Which harmonic is this? b) What is the wavelength of this wave?
