What is the amplitude of longitudinal wave?

1. The maximum distance from the equilibrium position of a vibrating object is called amplitude. The amplitude is equal to the maximum displacement value. The amplitude is a scalar, expressed in meters or centimeters. Amplitude describes the amplitude and intensity of vibration of an object.

2. Shear wave: In physics, the wave whose vibration direction is perpendicular to the wave propagation direction is called shear wave. In shear waves, the highest part of a bulge is called a peak, and the lowest part of a depression is called a trough.

3. Longitudinal wave: In physics, the wave in which the vibration direction of a particle and the propagation direction of the wave are in the same line is called longitudinal wave. When the longitudinal wave propagates, the particles vibrate back and forth, in which the densest particle distribution is called the dense part and the rarest particle distribution is called the sparse part.

4. No matter shear wave or longitudinal wave, the definition of their amplitude is the same, that is, the maximum distance from the equilibrium position. Only their amplitude directions are different.
