Waves

2. The lowest points on a transverse wave.
4. Horizontal row in the periodic table; the amount of time it takes one wavelength to pass a fixed point; is expressed in seconds.
5. The number of wavelengths that pass a fixed point each second; it is expressed in hertz (Hz).
8. Wave A wave pattern that follows when waves of equal wavelength and amplitude, but traveling in opposite directions, continuously interfere with each other; has points called nodes that do not move.
12. A measure of the energy carried by a wave.
13. A wave for which the matter in the medium moves back and forth at right angles to the direction the wave travels; has crests and troughs.
15. The bending of a wave as it changes speed in moving from one medium to another.
16. The bending of waves around an obstacle; can also occur when waves pass through a narrow opening.

1. A wave for which the matter in the medium moves back and forth along the direction the wave travels.
3. Distance between one point on a wave and the nearest point just like it.
6. The least dense regions of a compressional wave.
7. Occurs when two or move waves overlap and combine to form a new wave.
9. The highest points on a transverse wave.
10. The process by which an object is made to vibrate by absorbing energy at its frequencies.
11. A repeating disturbance or movement that transfers energy through matter or space.
14. Matter in which a wave travels.
