Answer:
amplitude/energy
Explanation:
The wave of a loud sound will have more amplitude or energy than a quiet one.
The intensity of a sound is depends on how loud the sound is. The louder the sound, the higher the intensity and vice versa.
The intensity of a sound also depends on the amount of energy the sound carries. The higher the intensity of the sound, the higher the energy carried by the sound.
Also, the amplitude of a wave depends on the energy the wave carries. The waves of a loud sound carry higher energy and as such, higher amplitude than the waves of a low/quiet sound.
Hence, a sound wave with loud sound will have more energy/intensity/amplitude than a sound wave with quiet sound.
