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
oscillation, vibration
(physics) a regular periodic variation in value about a mean
fluctuation
a wave motion
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
traveling wave, travelling wave
a wave in which the medium moves in the direction of propagation of the wave
acoustic wave, sound wave
(acoustics) a wave that transmits sound
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
impulse, pulsation, pulse, pulsing
(electronics) a sharp transient wave in the normal electrical state (or a series of such transients)
flap, flapping, flutter, fluttering
the motion made by flapping up and down
ripple
(electronics) an oscillation of small amplitude imposed on top of a steady value
solitary wave, soliton, soliton wave
(physics) a quantum of energy or quasiparticle that can be propagated as a traveling wave in nonlinear systems and is neither preceded nor followed by another such disturbance; does not obey the superposition principle and does not dissipate
air wave
a sound wave that is transmitted via air
transient
(physics) a short-lived oscillation in a system caused by a sudden change of voltage or current or load
sonic boom
an explosive sound caused by the shock wave of an airplane traveling faster than the speed of sound
beat
a single pulsation of an oscillation produced by adding two waves of different frequencies; has a frequency equal to the difference between the two oscillations
resonance
a vibration of large amplitude produced by a relatively small vibration near the same frequency of vibration as the natural frequency of the resonating system
sympathetic vibration
(physics) vibration produced by resonance
Type of:
motion, movement
a natural event that involves a change in the position or location of something

n an undulating curve

Synonyms:
wave
Types:
sine curve, sinusoid
the curve of y=sin x
Type of:
curve, curved shape
the trace of a point whose direction of motion changes
