In a wave the maximum displacement of particles from their equilibrium positions is called.
Answer Details
In a wave, the maximum displacement of particles from their equilibrium positions is called the amplitude. The amplitude represents the maximum height of a wave or the distance between the crest (highest point) and the trough (lowest point) of a wave. It is a measure of the wave's energy, and the greater the amplitude, the more energy the wave carries. For example, in a sound wave, the amplitude determines the loudness of the sound, and in a light wave, it determines the brightness of the light.
