The given wave has an amplitude of 1.5 units, which represents the maximum displacement from the equilibrium position. The period of the wave is 4 units of time, which is the time it takes for one complete cycle to occur.
To determine the amplitude and period of the given wave, we need to analyze the pattern of the displacement values.
The amplitude of a wave is the maximum displacement from the equilibrium position. In this case, the maximum displacement is 1.5 units (positive or negative). Therefore, the amplitude of the wave is 1.5.
The period of a wave is the time it takes for one complete cycle to occur. To determine the period, we need to identify the time it takes for the displacement values to repeat.
Looking at the given displacement values, we can observe that the pattern repeats every 4 units of time. From the first data point (1.5) to the seventh data point (-1.5), a complete cycle occurs. Therefore, the period of the wave is 4 units of time.
