look at the diagram. which point identifies a node? a b c d
Answer
Explanation:
Step1: Recall the definition of a node
A node is a point in a wave where there is no displacement (i.e., the wave has zero amplitude).
Step2: Analyze each point
- Point A: It is at a position of maximum displacement (an antinode).
- Point B: It is at a position of zero displacement (a node).
- Point C: It is at a position of maximum displacement (an antinode).
- Point D: It is at a position of maximum displacement (an antinode).
Answer:
B
