Question

Wave A has a long fetch. Wave B has a short fetch. Which of the following statements is true? Wave A is more powerful than Wave

b. Wave B is more powerful than Wave
a. Both waves are equally powerful.

Answer 1

The following statement that is true is : wave A is more powerful than wave B

Longer Fetch tend to create a higher energy level, which make the wave with longer fetch is stronger than the one with shorter fetch

Answer 2

Correct answer is

wave A is more powerful than wave B

Step-by-step explanation

Fetch of a wave is the length of water over which a wind blow. It is clear that the wave which has longer fetch will have higher energy level. And higher energy level wave will be more powerful that wave which has short fetch. hence wave A which has longer fetch than wave B will be more powerful that wave B.
