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