Exam-style question
Try this first
In a stationary wave, what are nodes and antinodes? Describe their positions in relation to the wave's amplitude.
Model answer
What a good answer should say
- Nodes are points on a stationary wave where there is no displacement, while antinodes are points where the displacement is maximum.
- Nodes occur at positions where destructive interference occurs, and antinodes occur at positions of constructive interference, typically halfway between nodes.
Explanation
Why this works
This question tests the understanding of stationary wave characteristics, specifically the definitions and positions of nodes and antinodes. A strong answer accurately describes both terms and their relationship to wave amplitude.
