undulation -
wavelike motion; a gentle rising and falling in the manner of waves
motion,
movement the act of changing location from one place to another; "police controlled the motion of the crowd"; "the movement of people from the farms to the cities"; "his move put him directly in my path"
undulation -
(physics) a movement up and down or back and forth
motion,

natural philosophy,
physics the science of matter and energy and their interactions; "his favorite subject was physics"
gravitation wave,
gravity wave (physics) a wave that is hypothesized to propagate gravity and to travel at the speed of light
sine wave a wave whose waveform resembles a sine curve
fluctuation the quality of being unsteady and subject to changes; "he kept a record of price fluctuations"
seiche a wave on the surface of a lake or landlocked bay; caused by atmospheric or seismic disturbances
standing wave,
stationary wave a wave (as a sound wave in a chamber or an electromagnetic wave in a transmission line) in which the ratio of its instantaneous amplitude at one point to that at any other point does not vary with time
wave form,
wave shape,
waveform the shape of a wave illustrated graphically by plotting the values of the period quantity against time
blast wave,
shock wave a region of high pressure travelling through a gas at a high velocity; "the explosion created a shock wave"
pulsing,
pulsation,
pulse,
impulse (electronics) a sharp transient wave in the normal electrical state (or a series of such transients); "the pulsations seemed to be coming from a star"
