Question

If wave A has twice the amplitude and three times the frequency as wave B, then the energy carried by wave A must be ____ times that of wave B.

Answer 1

Answer:

4 times

Explanation:

As we know that the energy of a wave is directly proportional to the square of the amplitude of the wave,

Here, the amplitude of the wave A is twice as compared to B.

So, the energy of wave A is 4 times the energy of wave B.
