Question

What is the period of water wave if 4 complete waves pass a fixed point in 10 seconds?

Answer 1

Given:

To complete four waves, time taken is 10 s.

To find the time period of one wave.

Step-by-step explanation:

The time taken to complete 4 waves is

`4T\text{ = 10}`

The time period will be

`\begin{gathered} T=\text{ }(10)/(4) \\ =2.5\text{ s} \end{gathered}`

Thus, the time period of one wave is 2.5 s.
