Answer 1

Answer:

waves reaching you at the end of the pool.

You observed that at every 2-second interval 3 wave reaches you.

2) your friend decides to continue his repeated bobbing as he approaches you. As he did so you notice something else. Instead of 3, you observe 4 waves reaching you every 2 seconds.

3) So your friend decided to return to his previous position in the pool, still continuously bobbing. Your friend lost focus of his intention and went past his original position. You detected his loss of focus and decide to call out to him, This time instead of 3 waves per 2 seconds, you observe that only1 wave reaches you every 2 seconds,
