Final answer:
The amplitude of the wave shown is 1.0 cm.
Step-by-step explanation:
The amplitude of a wave represents the maximum displacement of the medium from its equilibrium position. It is the characteristic height of the wave above or below the equilibrium position. In the given wave, the amplitude can be measured by the distance between the crest and the equilibrium position or the trough and the equilibrium position. If you describe the wave, I can provide information about its amplitude. In general, amplitude refers to the maximum displacement of a wave from its equilibrium position. Looking at the options provided, the amplitude of the wave shown is 1.0 cm, which corresponds to Option 1.
