Question

9. Henry ties a rope to the handle of a door. He moves the rope up and down to make wavesi He begins moving it quicker and the wave almost seems to stand still. He has made a standing wave. The areas on the wave where the amplitude is zero are called and the areas on the wave where the amplitude is the greatest are known as​

Answer 1

nodes; antinodes

Step-by-step explanation:

For standing waves, the areas where the amplitude is zero are referred to as nodes while the areas where the amplitude is at the maximum are known as antinodes.

A standing wave derives its feature primarily from the fact that there are certain points along the medium of transmission that are apparently seeing to be standing still with no displacement whatsoever. At the same time, there exist opposing points to the points of zero displacements. These points have a maximum displacement in both the positive and negative directions. While the former is referred to as nodal points, the latter is known as the antinodal points.
