Across
- 2. Number of cycles per second in hertz
- 4. Machines make a task easier by reducing the force or distance needed
- 8. a wave’s energy dies out in a soft material
- 9. length of time for one cycle; how long it takes for one repetition
- 10. a wave bends when entering a transparent boundary.
- 13. is the reinforcing of an object’s natural frequency so that the amplitude increases quickly.
- 14. the result of that you put in
- 15. a wave bounces off when it hits a hard boundary
Down
- 1. goes from here to there: one direction.
- 3. a particular part of a cycle.
- 5. is any motion that is repetitive
- 6. Amount of force put in
- 7. part of a wave bends around a corner
- 11. When two waves interact they interfere with each other.
- 12. the repeated portion of the motion; includes all of the steps of the motion.
