Polarization requires transverse waves Steps:

• Polarization is the orientation of wave oscillations perpendicular to propagation, possible only in transverse waves.
• Electromagnetic waves (light, microwaves, radio) are transverse and polarizable; sound waves are longitudinal and not.
• Examine each option for inclusion of only electromagnetic waves.
• Identify the option excluding sound waves.

Why B is correct:

• Visible light, microwaves, and radio waves are all transverse electromagnetic waves, which can be polarized per the definition of transverse wave motion.

Why the others are wrong:

• A includes sound waves, which are longitudinal and cannot be polarized.
• C includes sound waves, which are longitudinal and cannot be polarized.
• D includes sound waves, which are longitudinal and cannot be polarized.

Final answer: B
