which refers to the density of the mediums particles at the compression of a sound wave?\no amplitude\no pitch\no volume\no wavelength
Answer
Brief Explanations:
Amplitude is related to the maximum displacement of particles in a wave. Pitch is related to frequency. Volume is related to the intensity of a sound wave. Wavelength is the distance between two - consecutive points in phase. The density of the medium's particles at the compression of a sound wave is related to the amplitude of the sound wave. A larger amplitude means more compression and higher density of particles at the compression region.
Answer:
amplitude
