Physics - Wave on String Question with Solution | TestHub

The frequency of the waves is the number of waves passing per second.

$n=\frac{45}{60}=0.75\text{ Hz}$

The wavelength is given as $\lambda =7\text{ m}$.

The velocity of the waves is given by the relation:

$v=n\lambda$

$v=0.75\times 7=5.25\text{ m/s}$

Answer: $5.25\mathrm{m}/\mathrm{s}$
