Physics - Wave on String Question with Solution | TestHub

Given velocity of waves, $v=10$ m/s.

Distance between two consecutive crests is the wavelength, $\lambda =40$ m.

The time interval between consecutive waves striking the stationary boat is the time period $T$.

Using the relation $v=\frac{\lambda }{T}$, we get:

$T=\frac{\lambda }{v}$

$T=\frac{40}{10}=4$ s.

Answer: $4$ s
