Question

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.

Answer 1

option (c)

Step-by-step explanation:

The wave transfer energy from one point to another without transfer of mass.

The energy of a wave is directly proportional to the square of the amplitude of the wave and also proportional to the square of the frequency of the wave.

Energy α amplitude²

Energy α frequency²

So, the wave which carries more energy it has more amplitude and high frequency.

Thus, option (c) is correct.

Answer 2

Step-by-step 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 .
