my teacher went over it and the answer was that
To answer the question above,
First, let's determine the speed of sound under the water.
S
peed of sound in water at 20oC = 1482m/s
<span>So λ = v/f = 1482m/s/(100kHz) I'm assuming your frequency is 100kHz </span>
<span>So λ would be = 0.0148m
I hope my answer helped you.</span>
