which wave, a or b, has lower energy? a, because it has a higher amplitude b, because it has a higher amplitude a, because it has a lower amplitude b, because it has a lower amplitude
Answer
Brief Explanations:
The energy of a wave is directly proportional to the square of its amplitude. Wave A has a lower amplitude than wave B, so wave A has lower energy.
Answer:
A, because it has a lower amplitude
