Across
  1. 3. Point of maximum amplitude when 2 pulses with equal displacements in the same direction meet
  2. 4. A single disturbance that travels through a medium
  3. 5. Those that consist of oscillating electric and magnetic fields that move at the speed of light through space
  4. 12. Shortest distance between 2 points where a wave pattern repeats itself.
  5. 15. Shortest time interval during which the motion repeats itself
  6. 17. Point that is undisturbed when 2 pulses with equal but opposite displacements
  7. 18. Causes particles in medium to vibrate to the direction of motion
  8. 19. Wave in which nodes and antidnodes are stationary
Down
  1. 1. Those consisting of periodic motion of matter
  2. 2. part of wave moves backward from boundary in old medium
  3. 6. Causes particles in medium to move to the direction of the wave
  4. 7. Highest point of each wave motion
  5. 8. change in direction of waves at boundary between media
  6. 9. Result of superposition
  7. 10. Maximum displacement from the rest or equilibrium position
  8. 11. A mixture of transverse and longitudinal waves
  9. 13. One which moves as a periodic, repetitious disturbance in a medium
  10. 14. Wave-like behaviour of particles, such as electrons
  11. 16. Number of complete vibrations per second measured at a fixed point
  12. 18. Lowest point of each wave motion
