Question

Use the two wave graphs to determine the speed of the graph

Answer 1

We will have the following:

*Frequency:

$f=\frac{5}{0.5s}\Rightarrow f=10Hz$

*Wavelength:

$\lambda=15m$

*Velocity:

$\begin{gathered} v=\lambda\ast f\Rightarrow v=(15m)(10Hz) \\ \\ \Rightarrow v=150m/s \end{gathered}$
