Wave amplitude is related to

A)wave velocity
B)frequency
C)energy
D)wavelength

Wave amplitude is related to C) energy.

To understand why, let's first define what wave amplitude is. Wave amplitude refers to the maximum displacement or distance that a particle in a wave medium moves from its equilibrium or rest position.

The energy of a wave is determined by the amount of mechanical energy it carries or transfers. When a wave travels through a medium, it causes particles in the medium to oscillate or vibrate. The energy associated with this oscillation is directly proportional to the square of the wave amplitude.

In other words, the more energy a wave carries, the greater the amplitude of the wave. This means that increasing the amplitude will result in an increase in the energy carried by the wave and vice versa. Conversely, decreasing the amplitude will result in a decrease in the energy carried by the wave.

So, wave amplitude is related to the energy carried by the wave, but it is not directly influenced by other factors listed in the options:

- Wave velocity (A) refers to the speed at which the wave propagates through a medium and is determined by the medium's properties. It does not directly affect the amplitude.
- Frequency (B) refers to the number of complete cycles or oscillations of a wave that occur in a given time. While frequency is related to the wave's energy, it is not a direct cause of amplitude changes.
- Wavelength (D) is the distance between two adjacent points in a wave that are in phase (e.g., two consecutive crests or two consecutive troughs). Wavelength and amplitude are related variables, but they are distinct from each other. Changes in wavelength do not directly affect the amplitude of a wave.

Therefore, the correct answer is C) energy.

Wave amplitude is related to C) energy.

The amplitude of a wave refers to the maximum displacement of a particle from its equilibrium position in the medium as the wave passes through it. It represents the energy carried by the wave. The greater the amplitude of a wave, the more energy it carries. Conversely, a smaller amplitude corresponds to a lower energy level. Therefore, amplitude and energy are directly related.
