Question on: SS1 Physics - Sound And Waves

The amplitude of a sound wave refers to the maximum displacement of particles in the medium caused by the wave. It represents the intensity or energy of the sound wave. The perceived loudness of a sound is directly related to the amplitude of the sound wave. Higher-amplitude sound waves create more significant displacements of particles and result in a greater sensation of loudness. In contrast, lower-amplitude sound waves produce quieter sounds.
