which refers to the amount of energy in a sound wave per unit of time and is also related to the loudness of a sound?\no period\no compression\no amplitude\no intensity
Answer
Brief Explanations:
The period is the time for one - complete cycle of a wave. Compression is part of a longitudinal wave where particles are close together. Amplitude is the maximum displacement of a wave from its equilibrium position. Intensity is the amount of energy in a sound wave per unit of time and is related to loudness.
Answer:
D. intensity
