Slightly downstream for the shortest possible time
Answer:
The answer is gravity
Explanation: Hope this helps:)
The amplitude of a wave can be obtained by measuring the distance from the resting position of the wave to its crest. The resting position is half of the distance from the crest to the trough. Given that the distance between the crest and the trough is 3 meters, the amplitude should be half of that, which is 1.5 meters.
