### Wave

Any surging or progressing movement or part resembling a wave of the sea

### Period

an amount of time

### Simple Harmonic Motion

periodic motion in which the restoring force is proportional to the displacement

### Crest

reach a high point

### Trough

the lowest point of a wave

### Amplitude

the maximum displacement of a periodic wave

### Wavelength

the distance (measured in the direction of propagation) between two points in the same phase in consecutive cycles of a wave

### Frequency

the number of occurrences of a wave within a given time period (usually 1 second)

### Hertz

the unit of frequency

### Transverse Wave

a wave that moves the medium in a direction perpendicular to the direction in which the wave travels

### Longitudinal Wave

a wave in which the vibration of the medium is parallel to the direction the wave travels

### Constructive Interference

The interference that occurs when two waves combine to make a wave with a larger amplitude.

### Destructive Interference

the interference that occurs when two waves combine to make a wave with a smaller amplitude

### Node

the point of minimum displacement in a periodic system

### Antinode

the point of maximum displacement in a periodic system

### Pitch

how high or low a sound is

### Compression

the part of a longitudinal wave where the particles of the medium are close together

### Rarefaction

the least dense region of a compressional wave

### Forced Vibration

the vibration of an object that is made to vibrate by another vibrating object

### Natural Frequency

frequencies at which an object will vibrate when it is struck or disturbed

### Resonance

the quality imparted to voiced speech sounds by the action of the resonating chambers of the throat and mouth and nasal cavities
