Across
  1. 4. Maximum displacement from the rest or equilibrium position
  2. 5. Lowest point of each wave motion
  3. 6. Point that is undisturbed when 2 pulses with equal but opposite displacements
  4. 7. Number of complete vibrations per second measured at a fixed point
  5. 9. Causes particles in medium to move to the direction of the wave
  6. 10. Causes particles in medium to vibrate to the direction of motion
  7. 13. Those consisting of periodic motion of matter
  8. 14. Shortest time interval during which the motion repeats itself
  9. 16. One which moves as a periodic, repetitious disturbance in a medium
  10. 18. part of wave moves backward from boundary in old medium

  12. 20. change in direction of waves at boundary between media
Down
  1. 1. Point of maximum amplitude when 2 pulses with equal displacements in the same direction meet
  2. 2. Wave-like behaviour of particles, such as electrons
  3. 3. Shortest distance between 2 points where a wave pattern repeats itself.
  4. 8. Those that consist of oscillating electric and magnetic fields that move at the speed of light through space
  5. 11. Wave in which nodes and antidnodes are stationary
  6. 12. A mixture of transverse and longitudinal waves
