Question

What is the wavelength of the waves you create in a swimming pool if you splash your hand at a rate of 1.41 Hz and the waves propagate at a wave speed of 5.54 m/s?

Round your answer to 2 decimal places.

Pls do not forget the unit

Answer 1

$$\lambda=\frac{v}{f}=\rm\frac{5.54\: m/s}{1.41\: Hz}=3.93\:\rm m$$
