- 1WaveA repeated disturbance or movement that carries energy but not matter.
- 2MediumMatter through which a wave travels.
- 3Mechanical WaveA wave that can only travel through a medium, not a vacuum.
- 4Compressional WaveA mechanical wave in which the medium moves parallel (back and forth) to the direction the wave travels; longitudinal wave
- 5Transverse WaveA mechanical wave in which the medium moves perpendicular (up and down) to the direction the wave travels.
- 6CompressionThe region on a longitudinal wave where the medium is more dense or compressed.
- 7RarefactionThe region on a longitudinal wave where the medium is more dense or compressed.
- 8AmplitudeA measure of the energy a wave carries
- 9WavelengthThe distance from one point on a wave to the nearest point just like it.
- 10FrequencyThe number of wavelengths that pass a point in a second.
- 11PeriodThe amount of time it takes one wavelength to pass a point.
- 12ReflectionWhen waves bounce off an object
- 13RefractionWhen waves bend passing through an object.
- 14DiffractionWhen waves bend passing around an object.
- 15Constructive InterferenceWhen in phase waves overlap and combine to create a larger wave.
- 16Destructive InterferenceWhen out of phase waves overlap and cancel out to create a smaller wave.
- 17IntensityThe amount of energy that passes through an area in a unit of time; also related to the loudness and amplitude of a sound wave.
- 18PitchHow high or low a sound is.
- 19Doppler effectChange in pitch due to a moving wave source.
- 20How are waves created? What do they carry?Waves are created by vibrations. As waves travel, they carry energy, but never matter.
