Answer :
We are asked to determine the wavelength of a wave that travels with a velocity of 23.8 m/s and has a frequency of 11 Hz. To do that we will use the following formula:-
[tex]v=f\lambda[/tex]Where:
[tex]\begin{gathered} v=\text{ wave velocity} \\ f=\text{ frenquency} \\ \lambda=\text{ wavelength} \end{gathered}[/tex]Now, we solve for the wavelength by dividing both sides by the frequency:
[tex]\frac{v}{f}=\lambda[/tex]Plugging in the values we get:
[tex]\frac{23.8\frac{m}{s}}{11Hz}=\lambda[/tex]Solving the operations we get:
[tex]2.2m=\lambda[/tex]Therefore, the wavelength is 2.2 meters.
