Wave amplitude is related to what?

(a) wave velocity (b) frequency
(c) energy (d) wavelength

Wave amplitude is related to the intensity or energy of a wave. The correct answer is (c) energy.

To understand this relationship, it is helpful to first define wave amplitude. Amplitude refers to the maximum displacement or distance that a wave moves from its equilibrium position. In other words, it measures the maximum magnitude or strength of the wave.

The energy of a wave is directly proportional to its amplitude. This means that as the amplitude of a wave increases, so does its energy. The greater the displacement of a wave from its equilibrium position, the more energy it carries.

To determine the amplitude of a wave experimentally, one can measure the maximum displacement of the wave from its equilibrium position. Alternatively, if the wave is represented by a mathematical equation, the amplitude can be determined by examining the height of the wave on a graph.

While wave amplitude is related to energy, it is important to note that it is not related to wave velocity (a), frequency (b), or wavelength (d). Wave velocity represents the speed at which a wave travels through a medium, frequency refers to the number of wave cycles per unit of time, and wavelength measures the distance between two consecutive points on a wave. Although these factors influence various properties of a wave, they do not directly affect wave amplitude.

The energy per volume is proportional to the square of the amplitude. The wave power is also proportional to wave speed. Take your pick
