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
