1.
The maximum displacement on either side of the equilibrium (midpoint) position.
2.
A wave that moves the medium in a direction perpendicular to the direction in which the wave travels.
3.
A wave in which the vibration of the medium is parallel to the direction the wave travels.
4.
Lowest point of a wave.
5.
Horizontal distance between the crests or between the troughs of two adjacent waves.
6.
The number of wavelengths that pass by a point each second.
8.
position The place where no waves are being produced; no energy present.
9.
The part of a longitudinal wave where the particles of the medium are close together.
10.
A part in a longitudinal wave where the particles are spread apart.
11.
A form of energy that can move through the vacuum of space.
12.
A wave that requires a medium through which to travel.
13.
Material through which a wave travels.
14.
The transfer of energy by a wave to the medium through which it travels.
15.
Pertaining to building or putting parts together to make a whole.
16.
A change in the direction of a wave when the wave finds an obstacle or an edge, such as an opening.
17.
The combination of two or more waves that results in a single wave.
18.
The bouncing back of a wave when it hits a surface through which it cannot pass.
19.
Wave changes direction because its speed changes.
20.
The passage of light through an object.
21.
Highest point of a wave.
