Question

Which of the following statements are true?
i) Direction of wave propagation and particle motion are along the same direction for longitudinal waves
ii) Direction of wave propagation and particle motion are along the same direction for Transverse waves
iii) Direction of wave propagation and particle motion are perpendicular to each other for longitudinal waves
iv) Direction of wave propagation and particle motion are perpendicular to each other for transverse waves

  1. I and iv are correct
  2. I and iii are correct
  3. ii and iv are correct
  4. ii and iii are correct

hintHint:

Definition of longitudinal and transverse waves

The correct answer is: I and iv are correct


    In transverse waves, the displacement of the particle is perpendicular to the direction of propagation of the wave. In a longitudinal wave, the displacement of the particle is parallel to the direction of the wave propagation
