Kaden is making waves using a string tied to a doorknob. He moves the string up and down and creates four waves, as shown in the picture below. Kaden wants to create more than four waves using the same piece of string. What could he do to create more waves in the same amount of time?
A.
hold the string tighter as he moves it up and down
B.
pull the string away from the wall before moving it up and down
C.
move the end of the string up and down more quickly
D.
move the end of the string up and down more slowly

C

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.
