Exam-style question
Try this first
Describe what happens to the particles in a longitudinal wave during a compression and a rarefaction.
Model answer
What a good answer should say
- In a longitudinal wave, during a compression, particles are pushed closer together, resulting in an area of high pressure.
- In a rarefaction, particles are spread further apart, creating an area of low pressure.
Explanation
Why this works
This answer is strong because it accurately describes the behavior of particles in longitudinal waves, focusing on the key concepts of compression and rarefaction. The question tests the understanding of wave mechanics and particle movement.
