Detailed explanation-1: -The energy transported by a wave is directly proportional to the square of the amplitude. So whatever change occurs in the amplitude, the square of that effect impacts the energy. This means that a doubling of the amplitude results in a quadrupling of the energy.

Detailed explanation-2: -The wave’s amplitude and frequency are related in such a way that they are inversely proportional to one another. The amplitude decreases with increasing frequency. The amplitude increases as the frequency decreases.

Detailed explanation-3: -Mechanical Waves: Mechanical waves can change speed as they move forward through matter due to changes in the physical properties of matter and how they affect the properties of the wave. As mechanical waves always depend on matter as their medium to travel, most waves will change speed at some point.
