Polarization requires transverse waves. Sound in air is longitudinal (oscillations ∥ propagation) ⇒ cannot be polarized. EM waves (light, radio, X-rays) are transverse ⇒ can be polarized. Memory tip: 'Polarization ⇒ transverse only; sound = longitudinal ⇒ no polarization'. Wave property frequently tested in competitive exams.
