Longitudinal waves do not exhibit

A. refraction

B. polarization

C. diffraction

D. reflection

QUICK ANSWER…

B

DETAILS…

Only transverse waves can be plane polarized, this is because polarization involves the constricting of waves travelling in different planes into a particular plane.

Transverse waves are waves whose particle vibrations are perpendicular to the direction of travel of their waves example: electromagnetic waves.

Longitudinal waves are waves whose particle vibrations are parallel to the direction of travel of their waves, this makes it impossible to polarize since the vibration move in the same direction as the direction of wave travel.

Now for the right answer to the above question:

  1. Option A is incorrect. longitudinal waves like sound can be refracted.
  2. Option B is correct. longitudinal waves like sound cannot be polarized.
  3. C is incorrect. sound waves can be diffracted.
  4. D is not the correct answer. sound waves can be reflected as echoes.

KEY-POINTS…

You may please note these/this:

  • Longitudinal waves cannot be polarized because their particle vibrations and waves move in the same direction.
