Problem

A mechanical oscillator drives a transverse wave along a string of linear mass density

\mu = 4.0\times10^{-3}\,\text{kg/m}

under a tension of

80\,\text{N}

. The oscillator operates at

120\,\text{Hz}

. If the tension is increased to

200\,\text{N}

while the driving frequency remains unchanged, what will be the new wavelength on the string? a)

1.2\,\text{m}

1.9\,\text{m}

0.74\,\text{m}

3.0\,\text{m}
