Question

Which of the following waves can be polarized?

• A. Transverse waves
• B. Tsunami waves
• C. Vibration of the drums
• D. Music woofers

Answer 1

The correct option is A

Transverse waves

The explanation for the correct option:

Polarization:

1. Transverse waves can oscillate perpendicular to their transmission direction, but longitudinal waves can only oscillate along their transmission direction. These transverse waves are referred to as S-waves or shear waves, and they can be polarised.
2. SH- waves are polarised in the horizontal direction, while SV- waves are polarised in the vertical direction.
3. As a result, a forward-moving light wave can vibrate up and down (in the vertical plane), side to side (in the horizontal plane), or somewhere in between.

Hence, Option(A) is correct.

The explanation for incorrect options:

1. Longitudinal waves, such as sound waves, cannot be polarised because particle motion is one-dimensional. As a result, because ultrasonic waves are sound waves, they cannot be polarized.
2. Tsunami waves, the vibration of the drums, and music woofers produce longitudinal waves.

Hence, Options(B),(C) and (D) are correct.

Hence, Option(A) is correct.
