The lowest A on a piano has a frequency of 27.5 Hz. If the tension in the 2.00-m string is 308 N, and one-half wavelength occupies the string, what is the mass of the wire?
a. 0.025 kg
b. 0.049 kg
c. 0.051 kg
d. 0.081 kg
e. 0.037 kg

Question 2

Transverse waves are traveling on a 1.00-m long piano string at 500 m/s. If the points of zero vibration occur at one-half wavelength (where the string is fastened at both ends), find the frequency of vibration.
a. 250 Hz
b. 500 Hz
c. 1 000 Hz
d. 2 000 Hz
e. 2 500 Hz
