Question 5

Explain why sound waves cannot be plane polarized
This question was popular among the candidates and was well attempted. However, the knowledge that only transverse wave can be plane polarized which is required to solve this problem eluded few candidates who attempted the question.


The expected answer is:
Polarization is a characteristic of only transverse waves. Since sound waves are longitudinal they cannot be plane polarized
