What is the amplitude of 1m and 6m?

The amplitude refers to the maximum extent of a wave's oscillation or displacement from its equilibrium position. If you're comparing two values, 1 meter and 6 meters, the amplitude could be described as the difference between them, which is 5 meters. Alternatively, if you're referring to the amplitude of a wave, it would be the maximum value, so in this case, the amplitude would be 6 meters.
