Across
  1. 2. the lowest part of a transverse wave
  2. 3. when light or sound bends
  3. 5. type of lens that makes light diverge
  4. 8. increase the frequency and the _____________ decreases
  5. 9. dense, sound will travel faster through glass than air because glass is ______ _________
  6. 13. part of a longitudinal wave that is close together
  7. 16. lower energy and low frequency, used in Wifi and communication
  8. 17. type of lens that can make a real inverted image on the opposite side of the lens
  9. 18. high energy and frequency wave used in airport security
  10. 20. light or sound enters a medium and stops
Down
  1. 1. type of wave where the energy and matter travel parallel, example is sound wave
  2. 4. travels fastest in a vacuum
  3. 6. light or sound travels through an object
  4. 7. the part of a wave that changes when the volume increases
  5. 10. when a bat travels using echolocation, the sound waves use this behavior
  6. 11. type of electromagnetic wave used in remote controls
  7. 12. waves that require a medium in which to travel
  8. 14. type of lens that can make a virtual image that is larger, light converges
  9. 15. when frequency of sound wave changes the _______ changes
  10. 19. waves, used for communication, longest wavelength and lowest energy
