**Step-by-Step Solution:** 1. **Understanding the Term Amplitude:** - Amplitude refers to the maximum displacement of particles in a medium from their equilibrium position when a wave passes through. In simpler terms, it measures how far the particles move from their rest position during the wave's oscillation. 2. **Defining Amplitude:** - The amplitude of a wave is defined as the maximum displacement of the particles of the medium on either side of their equilibrium position. This means that if you visualize a wave, the amplitude is the height of the wave from the center line (equilibrium position) to the peak (crest) or the lowest point (trough). ...
