### Crest

the highest point of a wave

### Amplitude

the maximum distance that the particles of a wave's medium vibrate from their rest position

### Diffraction

the bending of waves around a barrier or through an opening

### Frequency

the number of complete waves that pass a given point in a certain amount of time

### Hertz

the unit of frequency, equal to one cycle per second

### 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

### Longitudinal wave

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

### Mechanical wave

waves that transfer energy through matter

### Medium

the material through which a wave travels

### Period

the amount of time it takes one wavelength to pass a point

### Reflection

the action of a wave bouncing off an object

### Refraction

The bending of a wave as it passes at an angle from one medium to another

### Transverse wave

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

### Trough

the lowest point of a wave

### Wavelength

the distance between the crest of one wave and the crest of the next wave
