Question

Why can we polarise light waves but not sound waves?

Answer 1

So there is nothing to polarize. ... Light can be polarized because it is a transverse wave, so oscillations can begiven a particular orientation relative to the direction the wave is traveling.Sound consists of longitudinal wavesin the air—the direction of oscillationcan only be in the direction the wavetravels.

Answer 2

Hey Mate,

Here Is Your Answer

____________

Only transverse waves can be polarised. Longitudinal waves cannot be polarised. So,The Light Waves Are Transverse Waves And Sound Waves Are Longitudinal Waves.

Transverse: vibrations perpendicular to the direction of travel of the wave .
Longitudinal: vibrations parallel to the direction of travel of the wave.
