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 dont forget the unit

Answer 1

$$λ=v/f\\ =\rm (5.54 \:m/s)/(1.41\:Hz)=3.93\:m$$
