Across
  1. 2. movement of vibrations of matter
  2. 4. the point on a wave with the maximum value of upward displacement within a cycle
  3. 6. describes the maximum extent of a vibration, oscillation or wave measured from the position of equilibrium
  4. 7. the number of crests of a wave that move past a given point in a given unit of time
  5. 8. vibration of electric & magnetic fields
  6. 11. the distance between successive crests of a wave, especially points in a sound wave or electromagnetic wave
Down
  1. 1. the direction of the wave travel is perpendicular to the direction of the vibrating source
  2. 3. Unit of frequency
  3. 5. the direction of the wave travel is along the direction in which the source vibrates
  4. 9. an elongated area of lower air pressure
  5. 10. the time taken for one complete cycle of vibration, wave, or oscillation to pass a given point
