Answer:
The amplitude of the wave
Step-by-step explanation:
A wave can be defined by using several characteristics:
- The amplitude of a wave is the maximum displacement of the wave from its equilibrium position
- The wavelength of a wave corresponds to the distance between two adjacent points of the wave with same shape (e.g. the distance between two consecutive crests)
- The period of a wave corresponds to the time taken for one complete oscillation of the wave to occur
- The frequency of a wave corresponds to the number of complete oscillations of the wave in one second
In this problem, we are told that the height of the wave from equilibrium is 1 meter: based on the definitions above, we can say that this parameter corresponds to the amplitude of the wave.
