Waves

TermDefinition
Wave Repeating disturbance or movement that transfers energy through matter or space
Medium The matter the waves travel through
Transverse Wave In this type of wave, matter in the medium moves back and forth at right angles to the direction that the wave travels; has crests and troughs
Compressional Wave In this type of wave, matter in the medium moves back and forth along the same direction that the wave travels.
Crest Alternating high points in a transverse wave
Trough Alternating low points in a transverse wave
Rarefaction Less-dense regions of a compressional wave
wavelength The distance between one point on a wave and the nearest point just like it.
frequency The number of wavelengths that pass a fixed point each second.
period Amount of time it takes one wavelength to pass a point.
amplitude Related to the energy transferred by a wave; The greated it is, the more energy the wave transfers.
Refraction The bending of a wave caused by a change in its speed as it moves from one medium to another
Diffraction Occurs when an object causes a wave to change direction and bend around it.
interference When two or more waves overlap and combine to form a new wave
standing wave A special type of wave pattern that forms when waves equal in wavelength and amplitude, but travel in opposite directions, continuously interfere with each other.
resonance The process by which an object is made to vibrate by absorbing energy at its natural frequencies
