Across
  1. 3. Number of wave cycles per second measured in hertz (higher frequency means higher pitch sound or more energy)
  2. 6. WAVES Waves that can travel through empty space and do not need a medium (like light from the sun or radio signals)
  3. 8. A disturbance that transfers energy through a medium without permanently moving the medium itself (like a ripple on a pond)
  4. 9. Lowest point of a wave (like the bottom of an ocean wave)
  5. 10. Half the height of a wave from its resting position to peak (taller amplitude means louder sound or brighter light)
  6. 12. Material that carries a wave; only mechanical waves need one (like water for ocean waves or air for sound)
Down
  1. 1. WAVE Wave where particles vibrate parallel to the direction the wave travels (like a sound wave pushing air molecules)
  2. 2. Distance between two consecutive crests or troughs (shorter wavelength means higher pitch sound or bluer light)
  3. 4. Highest point of a wave (like the top of an ocean wave)
  4. 5. WAVE Wave where particles vibrate perpendicular to the direction the wave travels (like a wave on a string or visible light)
  5. 7. WAVES Waves that require a medium and cannot travel through empty space (like sound or water waves)
  6. 11. Time for one complete wave cycle (like the time between two ocean wave peaks)
