    • What is the direction of displacement in a transverse pulse?

  • Parallel to the direction of motion of the pulse
  • In a circular motion around the direction of motion of the pulse
  • Perpendicular to the direction of motion of the pulse (correct)
  • At an angle to the direction of motion of the pulse

    • What is measured in meters (m) in a pulse?

  • Frequency
  • Pulse length
  • Amplitude (correct)
