Question

the maximum displacement of a particle in a wave motion ia called ?​

Answer 1

Answer:

For a longitudinal wave, such as a sound wave, amplitude is measured by the maximum displacement of a particle from its position of equilibrium.

Displacement is usually used to describe particles in motion, as in how far a particle has moved from a given point. The wavelength in a longitudinal wave refers to the distance between two consecutive compressions or between two consecutive rarefactions.
