Acoustic

7. One string of a certain musical instrument is 80 cm long and has mass of 8,72 gram. It is being played in a room where the speed of sound is 344 m/s.

a. To what tension must you adjust the string so that, when vibrating in its second overtone, it produces sound of wavelength 3,40 cm?

b. What frequency sound does this string produce in its fundamental mode of vibration?

The harp is a stringed musical instrument that has a number of individual strings running at an angle to its soundboard; the strings are plucked with the fingers to produce a sound. The strings can be made tighter or looser through the use of tuning pins (see the image below – for this question you can ignore the effects of the soundboard and pedals). Describe in detail what determines the frequency of sound of each string when it is plucked...
