Is the maximum distance the particles of the medium move from their resting positions when a wave passes through.

Amplitude

Explanation:

A wave is a periodic oscillation that carries energy, but not matter, through space or through a medium.

A wave is characterized by the fact that the particles in the medium oscillate around a fixed point, but there is no overall movement of particles in the direction of the wave (this means, only energy is transferred, while matter is not transferred).

A wave is also characterized by several properties, namely:

Amplitude: it is the maximum distance the particles of the medium move from their resting positions

Frequency: the number of oscillations of a certain particle per second

Wavelenght: the distance between two points of the wave that have same shape

Period: the time it takes for one particle of the wave to complete one oscillation

So, the answer is

Amplitude
