The amplitude of a wave is the maximum displacement or distance from equilibrium position of a particle in a medium as it oscillates or vibrates. In other words, it is the measure of the magnitude or strength of a wave. For example, in a transverse wave (like a water wave or a wave on a string), the amplitude is the maximum height or distance from the undisturbed or equilibrium position. In a longitudinal wave (like a sound wave), the amplitude is the maximum compression or rarefaction of the particles in the medium. The amplitude of a wave is often represented by the symbol "A" and is measured in units such as meters (m) or any other appropriate unit depending on the type of wave.
The amplitude of a wave refers to the maximum displacement or distance from equilibrium that a particle in the wave undergoes. It is a measure of the intensity or strength of the wave. To find the definition of the amplitude of a wave, you can consult various sources such as textbooks, encyclopedias, or reputable online resources.
