Problem

A string of length

1.2\,\text{m}

fixed at both ends is set into vibration. Two successive resonant frequencies are measured to be

200\,\text{Hz}

and

240\,\text{Hz}

. What is the speed of transverse waves on the string? a)

160\,\text{m}\,\text{s}^{-1}

48\,\text{m}\,\text{s}^{-1}

96\,\text{m}\,\text{s}^{-1}

480\,\text{m}\,\text{s}^{-1}
