Wave 1 carries more energy than Wave 2. Wave 3 carries more energy than Wave 2. Keeping speed constant, the greatest amount of energy is carried by a wave with–A a low amplitude and a high frequency. B a low amplitude and a low frequency. C a high amplitude and a high frequency. D a high amplitude and a low frequency.

Explanation:

Energy of a wave is proportional to ( amplitude )²

it is also proportional to ( frequency )²

It is proportional to velocity

Here velocity is constant

energy of wave ∝ ( amplitude )² x ( frequency )²

So,  option C a high amplitude and a high frequency is correct .
