Exam-style question
Try this first
Describe the characteristics of nodes and antinodes in a stationary wave.
Model answer
What a good answer should say
- Nodes are points along a stationary wave where there is no displacement, while antinodes are points where the displacement is at a maximum.
- The distance between two consecutive nodes or antinodes is half the wavelength of the wave.
Explanation
Why this works
This answer effectively distinguishes between nodes and antinodes, demonstrating knowledge of wave properties. It tests the student's ability to describe key features of stationary waves.
