TermDefinition
amplitude related to the energy carried by a wave.
compressional wave matter in the medium moves back and forth along the same direction that the wave travels.
crest an alternating high point
diffraction occurs when an object causes a wave to change direction and bend around it.
frequency the number of wavelengths that pass a fixed point each second.
interference when two or more waves overlap and combine to form a new wave.
medium the matter the waves travel through.
period the amount of time it takes one wavelength to pass a point.
rarefaction less-dense region of a compressional wave.
refraction the bending of a wave caused by a change in its speed as it moves from one medium to another.
resonance the process by which an object is made to vibrate by absorbing energy at its natural frequencies.
standing wave a special type of wave pattern that forms when waves equal in wavelength and amplitude, but traveling in opposite directions, continuously interfere with each other.
transverse wave matter in the medium moves back and forth at right angles to the direction that the wave travels.
trough an alternating low point
wave a repeating disturbance or movement that transfers energy through matter or space.
wavelength the distance between one point on a wave and the nearest point just like it.
