Across
- 3. The distance between one point on a wave and the nearest point just like it
- 4. Matter through which a wave travels
- 6. The number of wavelengths that pass a fixed point each second; is expressed in hertz (Hz)
- 11. The less-dense region of a longitudinal wave
- 12. The amount of time it takes one wavelength to pass a fixed point, expressed in seconds
- 14. 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 travelling
- 15. The process of two or more waves overlapping and combining to form a new wave
- 17. A measure of the size of the disturbance of a wave, related to the energy that it carries
- 18. A point in a standing wave at which the interfering waves always cancel
- 19. The process by which an object is made to vibrate by absorbing energy at its natural frequencies
Down
- 1. A repeating disturbance that transfers energy as it travels through matter or space
- 2. A wave in which the matter in the medium moves at right angles to the direction of the wave, has crests and troughs
- 5. The bending of waves around an obstacle; can also occur when waves pass through a narrow opening
- 7. The bending of a wave caused by a change in its speed as it travels from one medium to another
- 8. The highest point or peak of the wave, the point where the displacement of the medium is at a maximum
- 9. A wave in which the matter in the medium moves back and forth along the direction that the wave travels
- 10. The highest point or peak of the wave, the point where the displacement of the medium is at a maximum
- 13. A wave that can only travel through matter
- 16. The denser region of a longitudinal wave
