Question

heather and haley are modeling the movement of a wave using a rope. when heather gives one end of the rope a quick up and down shake, a wave travels down the rope toward haley. look at the picture of the rope model shown below.which arrow in the picture shows the amplitude of the wave?○a. x○b. z○c. y○d. w

Explanation:

The amplitude of a wave is defined as the maximum distance a point on the wave moves from its resting (equilibrium) position. Arrow X measures the vertical distance from the flat rope (rest position) to the peak of the wave, which matches the definition of amplitude. Arrow Z represents wavelength, arrow Y is a smaller vertical distance not reaching the peak, and arrow W represents the total length of the rope setup.

Answer:

A. X
