amplitude
the maximum displacement from equilibrium
antinode
a point in a standing wave, halfway between two nodes, at which the largest amplitude occurs
constructive interference
interference in which individual displacements on the same side of equilibrium position are added together to form the resultant wave
crest
the highest point above the equilibrium position
destructive interference
interference in which individual displacements on opposite sides of the equilibrium position are added together to form the resultant wave
frequency
the number of cycles or vibrations per unit of time
longitudinal wave
a wave whose particles vibrate parallel to the direction of wave motion
mechanical wave
a wave that propogates through a deformable, elastic medium
medium
the material through which a disturbance travels
node
a point in a standing wave that always undergoes complete destructive interference and therefore is stationary
period
the time it takes to execute a complete cycle of motion
periodic wave
a wave whose source is some form of periodic motion
pulse wave
a single nonperiodic disturbance
simple harmonic motion
vibration about an equilibrium position in which a restoring force is proportional to the displacement from equilibrium
standing wave
a wave pattern that results when two waves of the same frequency, wavelength, and amplitude travel in opposite directions and interfere
transverse wave
a wave whose particles vibrate perpendicular to the direction of wave motion
trough
the lowest point below the equilibrium position
wavelength
the distance between two adjacent similar points of the wave, such as from crest to crest or from trough to trough
