A 52.0 cm long cord is vibrating in such a manner that it forms a standing wave with two antinodes. (The cord is fixed at both ends.) (a) Which harmonic does this wave represent? first harmonic second harmonic third harmonic fourth harmonic none of the above (b) Determine the wavelength (in cm) of this wave. cm (c) How many nodes are there in the wave pattern? 1 2 3 4 none of the above (d) What If? If the cord has a linear mass density of 0.00526 kg/m and is vibrating at a frequency of 349.2 Hz, determine the tension (in N) in the cord. N The tension in a nylon monofilament fixed at both ends is 19.0 N. The mass per unit length is 6.00 x 10'3 kg/m, and its length is 19.0 cm. (a) What is the fundamental frequency (in H2)? Hz (b) What are the next three frequencies (in Hz) that could result in standing wave patterns? List them smallest to largest. second harmonic Hz third harmonic Hz fourth harmonic Hz
