Question

a snapshot of a periodic wave is modeled below. each square on the grid represents 1 unit. what is the waves amplitude? units related content waves wave properties 7:56 article wave properties

Explanation:

Step1: Recall Amplitude Definition

Amplitude of a wave is the maximum distance from the midline (equilibrium position) to the peak (or trough) of the wave.

Step2: Analyze the Grid

Each square is 1 unit. Looking at the wave, from the midline (the horizontal line) to the peak (or trough), we count the number of units. Observing the graph, the vertical distance from the midline to a peak (or trough) is 3 units (since it spans 3 squares, each of 1 unit).
