Across
- 2. The distance between any two corresponding points that are adjacent on a wave
- 9. the energy an object has due to its motion
- 11. can travel through space (vacuum)
- 12. the transfer of the energy of a wave to matter as the wave passes through it
- 14. distance between the resting position and the maximum displacement of the wave
- 15. an educated guess about what will happen in your experiment
- 19. are the particles in an atom that has a neutral charge
- 20. a physical material that humans need and value
- 21. an elementary particle that has a negative charge of electricity and travels around the nucleus of an atom

- 24. measured in hertz (Hz)
- 25. A compound breaks down into two substances (an element and a compound)
- 26. Measurement of speed and direction of an object
Down
- 1. abrupt change in the direction of propagation of a wave that strikes the boundary between different mediums
- 3. how plants produce their food
- 4. the highest surface part of a wave
- 5. the ability to do work
- 6. is the change in direction of a wave passing from one medium to another caused by its change in speed
- 7. a deep cup or glass with a wide mouth and usually a lip for pouring
- 8. is a physical property that measures how closely packed together a substance's particles are
- 10. is an atomic particle that occurs in the nucleus of every atom and carries a positive charge equal in size to the negative charge of an electron
- 13. is a measurement of how fast an object moves relative to a reference point
- 16. measured in decibels (Db)
- 17. the lowest part of a wave
- 18. when a wave travels through a medium or into a new medium
