Across
- 5. this wave requires a medium to travel
- 10. wavelength x frequency
- 11. a wave that vibrates in the same direction
- 13. the amount of energy in a wave
- 15. speed x time
- 16. wavelength is measured at the top of the wave
- 19. lowest point of a wave
- 21. distance from any point on one wave to the same point on the next wave
- 22. frequency is measured using this unit
- 24. bending of waves due to change in speed
Down
- 1. when matter is spread apart
- 2. matter a wave travels through
- 3. distance/time
- 4. the three items of matter are solid, _______, gas
- 6. highest point of a wave
- 7. _____ travels faster than sound waves
- 8. what other term shares the same equation with speed
- 9. you need this for a mechanical wave to work
- 12. when matter is pushed together
- 14. an example is when a water wave bends around a rock
- 17. this wave is a combination two mechanical waves
- 18. wavelength is measured at the bottom of the wave
- 19. a wave that vibrates the medium at right angles
- 20. bouncing back of a wave, for example a mirror
- 23. disturbance that transfers energy
