Question

a snapshot of a periodic wave is modeled below. each square on the grid represents 1 unit. what is the waves amplitude? units

Explanation:

Step1: Recall the definition of amplitude

The amplitude of a periodic wave is the maximum distance from the equilibrium (midline) to the peak (or trough) of the wave.

Step2: Determine the distance from midline to peak

Looking at the grid, the midline is the horizontal line (the black line). The peak of the wave is 2 units above the midline (since each square is 1 unit, and from the midline to the peak, we count 2 squares).
