In a longitudinal wave, amplitude can be measured from the distance between high pressure areas of the wave called crest.

The wave front of longitudinal wave consists of a lower depression called trough and inflated curve called crest.

The amplitude of the wave is known as the maximum displacement of the wave. This distance measured from the origin to maximum displacement of the wave gives amplitude of the wave.

Thus, we can conclude that, in a longitudinal wave, amplitude can be measured from the distance between high pressure areas of the wave called crest.

For longitudinal waves, amplitude is the distance from rest to crest.

Explanation:

Longitudinal Waves.

In a longitudinal wave the particle displacement is parallel to the direction of wave propagation.

longitudinal waves properties includes wavelength, amplitude, period, frequency and wave speed. However instead of peaks and troughs, longitudinal waves have compressions and rarefactions.

The amplitude of a wave refers to the maximum amount of displacement of a particle on the medium from its rest position. In a sense, the amplitude is the distance from rest to crest. Similarly, the amplitude can be measured from the rest position to the trough position.

For longitudinal waves, amplitude is the distance from rest to crest.

tube or goog with be a great resource to with that question

the independent variable, or the one that is intentionally manipulated is the speed.
