PLAY
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
