Across
- 3. the amount of time it takes one wavelength to pass a fixed point; is expressed in seconds.
- 6. the highest point on a transverse wave.
- 8. the less-dense region of a longitudinal wave.
- 11. a wave in which the matter in the medium moves back and forth along the direction that the wave travels.
- 14. denser region of a longitudinal wave.
- 15. distance between one point on a wave and the nearest point just like it.
- 17. a wave that can only travel through matter.
- 18. the process of two or more waves overlapping and combining to form a new wave.
- 19. a wave pattern that forms when waves of equal wavelength and amplitude, but traveling in opposite directions, continuously interfere with each other; does not appear to be traveling.
Down
- 1. the number of wavelengths that pass a fixed point each second; is expressed in hertz (Hz).
- 2. a point in a standing wave at which the interfering waves always cancel.
- 4. the process by which an object is made to vibrate by absorbing energy at its natural frequencies.
- 5. wave in which the matter in the medium moves at right angles to the direction of the wave, has crests and troughs.
- 7. the lowest point on a transverse wave.
- 9. the bending of waves around an obstacle; can also occur when waves pass through a narrow opening.
- 10. the bending of a wave caused by a change in its speed as it travels from one medium to another.
- 12. a repeating disturbance that transfers energy as it travels through matter or space.
- 13. matter through which a wave travels.
- 16. a measure of the size of the disturbance of a wave, related to the energy that it carries.
