Explanation:
Given that,
Each vertical line on the graph is 1 millisecond (0.001 s) of time.
We need to find the period and the frequency of the sound wave. The period of a wave is equal to the each vertical line on graph i.e. 0.001 s.
Let f be the frequency of the sound wave. So,
f = 1/T
i.e.

So, the period and the frequency of the sound waves is 1 milliseond and 1000 Hz respectively.

The action that humans can take to reduce wave erosion is to build breakwaters in the ocean.
<h3>What is erosion?</h3>
The term erosion has to do with the washing away of top soil either by water or by wind. The control of erosion is a very important soil conservation effort.
Hence, the action that humans can take to reduce wave erosion is to build breakwaters in the ocean.
