Question

A wave is measured and found to have a distance of 3.14 m between adjacent troughsand an amplitude of 1.54 m. What is the speed of the wave if the measured frequency is2.41 Hz?3.71 m/s0.768 m/s1.30 m/s7.57 m/s

Answer 1

$\begin{gathered} v=f\lambda \\ v=3.14m\cdot2.41Hz=7.57m/s \end{gathered}$
