  • B
    Longitudinal
  • C
    Both (A) and (B)
  • D
    None of the above

Answer

  1. Longitudinal
    Explanation:
    In longitudinal wave motion, the particles in the medium travel parallel to the direction of propagation of wave.
    In the given case, since the loaded spring applies force only in axial direction of the spring, hence the movement is also axial so the waves produced are longitudinal waves.
