Unformatted text preview: A 3. A violin string is 320m long between its fixed ends and has a mass of 2.2g. The open
string (no finger applied) sounds an A note (440 Hz). a. Calculate the tension in the string.
". What tension would be required for this open string to sound a C note (528 Hz)?
If instead of changing the tension you decide to sound a C note by stopping the string (pressing it against the Violin with your finger), how far from the end of the
string should it be applied? Lit,— qty—W, Or = /——-—-— .QQZZ
2" 32032} 4. A standing waveon a tight string experiment is set up in the laboratory. One end of
the string is attached to an oscillator that vibrates with a frequency of 60 Hz. The
other end of the string passes over a pulley and is attached to a mass. The distance
between the oscillator and the pulley is 1.2 in. When the oscillator is turned on, six
loops are observed on the string. The linear mass density of the string is 1.4 g/m.
