Given:
To complete four waves, time taken is 10 s.
To find the time period of one wave.
Explanation:
The time taken to complete 4 waves is
[tex]4T\text{ = 10}[/tex]
The time period will be
[tex]\begin{gathered} T=\text{ }\frac{10}{4} \\ =2.5\text{ s} \end{gathered}[/tex]
Thus, the time period of one wave is 2.5 s.
