Question

Which of the following cannot be polarized?

• A. Sound waves
• B. Light waves
• C. Radio waves
• D. X-rays

Hint:

Only transverse waves, such as light, radio, and X-rays, can be polarized. Longitudinal waves like sound cannot be polarized.

Answer 1

The Correct Option is A

Step 1: Understanding polarization.
Polarization refers to the orientation of oscillations in the direction perpendicular to the direction of the wave. Light waves, radio waves, and X-rays are transverse waves, meaning their oscillations can be polarized. However, sound waves are longitudinal waves, and they cannot be polarized.
Step 2: Elimination of options.
- (A) Sound waves: Sound waves are longitudinal waves and cannot be polarized.
- (B) Light waves: Light waves are transverse waves and can be polarized.
- (C) Radio waves: Radio waves are also transverse waves and can be polarized.
- (D) X-rays: X-rays are electromagnetic waves and can be polarized.
Conclusion: Sound waves cannot be polarized.
