Exam-style question
Try this first
Explain why longitudinal waves cannot be polarized.
Model answer
What a good answer should say
- Longitudinal waves cannot be polarized because their oscillations occur in the same direction as the wave travels, meaning there is no perpendicular component to filter out, which is necessary for polarization.
Explanation
Why this works
This answer effectively explains the fundamental reason behind the inability to polarize longitudinal waves, demonstrating a clear understanding of wave properties. The question assesses knowledge of wave behavior and characteristics.
