Question

Which wave cannot be polarized?

Answer 1

1. Longitudinal waves, such as sound waves, cannot be polarised because particle motion is one-dimensional or in a single line or in the direction it vibrates.
2. Longitudinal waves are waves where the displacement of the medium is parallel to the wave's direction of propagation.
3. Polarization is a process that affected radiation and especially light so that the vibrations of the wave assume a fixed form.
4. Polarization is possible for any transverse waves, including electromagnetic waves as their vibration, is perpendicular to the direction of energy travel.
