Problem

A string of length

1.20\,\text{m}

fixed at both ends vibrates in its second harmonic at

300\,\text{Hz}

when under tension

T_1

. The tension is then increased by

50\%

. What will be the frequency of the third harmonic under the new tension? a)

632\,\text{Hz}

675\,\text{Hz}

551\,\text{Hz}

450\,\text{Hz}
