Answer:
See below ↓
Explanation:
We know that the energy of a wave is directly proportional to the amplitude of a the wave. That means it directly varies, so when one increases/decreases, the other does the same.
Therefore, when the amplitude of a wave is doubled, the energy of the wave is also doubled.
Similarly, in the case of the frequency of the wave, it is also directly proportional to the energy of the wave.
⇒ E ∝ ν
