  1. APolarising axis
  2. BTransverse wave
  3. CPropagating axis
  4. DPass axis
Show answerHide answer

Correct answer: (B) Transverse wave

Explanation

Polarisation is possible only for transverse waves, because their vibrations are perpendicular to the direction of travel and so can be restricted to one direction. Longitudinal waves cannot be polarised.
