Question

directions: answer the question about amplitude.
what is the amplitude of the wave above?
meters

Explanation:

Step1: Recall amplitude definition

Amplitude is the maximum displacement from the equilibrium (rest) position.

Step2: Analyze the graph

The equilibrium position is the horizontal axis (y = 0). The wave's maximum displacement (peak or trough) from this axis: looking at the y - axis, the distance from 0 to the peak (or trough) is 1 unit? Wait, no, wait the y - axis has markings: from 0 to 1? Wait, no, the y - axis is labeled Distance (m), with marks at - 4, - 2, 0, 2, 4. Wait, no, the vertical axis: each small division? Wait, the wave goes from 0 up to 1? Wait, no, looking at the graph, the vertical axis (distance) has ticks: let's see, the equilibrium is at y = 0. The peak of the wave is at y = 1? Wait, no, maybe the scale: the vertical axis, from 0 to 1? Wait, no, the problem's graph: the vertical axis (distance) has labels - 4, - 2, 0, 2, 4, but the wave's amplitude: the maximum distance from the center (0) to a peak. Looking at the wave, the peak is at y = 1? Wait, no, maybe the small ticks: between 0 and 2, how many ticks? Wait, the graph shows that the wave's amplitude (maximum displacement from 0) is 1 meter? Wait, no, let's re - examine. The vertical axis (distance in meters) has a scale where from 0 to 2, there are two small ticks? Wait, no, the key is: amplitude is the height from the midline (equilibrium) to the peak. In the given graph, the midline is y = 0, and the peak is at y = 1 (since the distance from 0 to the peak is 1 unit). Wait, maybe the vertical axis: each small division is 1 meter? So the amplitude is 1 meter? Wait, no, wait the vertical axis labels: - 4, - 2, 0, 2, 4. But the wave's peaks are at y = 1? Wait, maybe the graph's vertical scale: the distance from 0 to the peak is 1 meter. So the amplitude is 1 meter. Wait, let's confirm: amplitude = maximum displacement from equilibrium. The equilibrium is y = 0. The wave's maximum y - value (peak) is 1 (since it goes up 1 unit from 0) and minimum (trough) is - 1. So amplitude is 1.
