Question

how many anti - nodes (bubbles) does this standing wave have? wave pattern select one. one two three four check

Explanation:

Step1: Identify Antinodes

Antinodes in a standing wave are the points of maximum displacement (the "bubbles" here). Looking at the wave pattern, we count the distinct regions of maximum displacement.

Step2: Count the Antinodes

The given wave pattern has three distinct antinodal regions (the three "bubbles" stacked vertically).

Answer:

Three (the option "Three")
