1.
The least dense regions of a compressional wave
2.
the number of wavelengths that pass a fixed point each second; expressed in hertz
3.
the bending of a wave as it changes speed in moving from one medium to another
4.
when two or more waves overlap and combine to form a new wave
5.
the process by which an object is made to vibrate by absorbing energy at its natural frequencies
6.
matter in which a wave travels
7.
a wave pattern that forms 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
8.
the amount of time it takes one wavelength to pass a fixed point; expressed in seconds
9.
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
10.
maximum distance a wave causes the particles in a medium to move from the rest position
11.
the lowest points on a transverse wave
12.
a wave for which the matter in the medium moves back and forth along the direction that the wave travels
13.
a repeating disturbance or movement that transfers energy through matter or space
14.
the highest points on a transverse wave
15.
distance between one point on a wave and the nearest point just like it
16.
the bending of waves around an obstacle; can also occur when waves pass through a narrow opening
