The period of a wave is equal to the time it takes for one wavelength to pass by a fixed point. You stand on a pier watching water waves and see 10.9 waves pass by in a time of 28 seconds. What is the period of the water waves? Round to nearest .01 and do not include units in your answer.

T = 2.57 s

Explanation:

The period of a wave is equal to the time it takes for one wavelength to pass by a fixed point.

No of waves observed = 10.9

Time taken, t = 28 s

We need to find the period of the water waves. Number of waves per unit time is called frequency. Let it is f. So,

If T is period of the wave. It is equal to the reciprocal of frequency.

So, the period of the water waves is 2.57 seconds.

i don't understand is there any other way you can rephrase it plz let me know in the comments and i will do it.

explanation:

i don’t know what the answer is i wish i
