oscillation
repetitive variation of some measure about a central value
Baryon acoustic oscillations
fluctuations in the density of the visible baryonic matter of the universe, caused by acoustic density waves in the primordial plasma of the early universe
noise
variety of sound, usually meaning any unwanted sound
plasma oscillation
rapid oscillations of the electron density in conducting media such as plasmas or metals
flicker
directly visible change in brightness of a light source: fluctuations of the light source itself, or rapid fluctuations in the voltage of the power supply or incompatibility with an external dimmer
neural oscillation
brainwaves, repetitive patterns of neural activity in the central nervous system
ground resonance
imbalance helicopter rotation when the blades become bunched in the rotational plane, typically on the ground when the landing gear is prevented from freely moving
periodic motion
periodic physical motion in which position oscillates
neutral particle oscillation
quantum mechanical transmutation of neutral particles
tide
rise and fall of sea levels caused by the combined effects of the gravitational forces exerted by the Moon and the Sun and the rotation of the Earth
Lamb waves
elastic waves propagating in solid plates or spheres
Antarctic oscillation
climatic cycle over the Southern Ocean
electronic oscillation
continuous recurrence of the same electrical periodic waveform
hunting oscillation
self-oscillation about an equilibrium that is usually unwanted
pulse
tactile arterial palpation of the heartbeat by trained fingertips
damping
reduction in motion of an oscillatory system through frictional forces
ringing
unwanted oscillation of a signal
Bloch oscillations
describes the oscillation of a particle confined in a periodic potential when a constant force is acting on it
Pacific decadal oscillation
robust, recurring pattern of ocean-atmosphere climate variability centered over the mid-latitude Pacific basin
Breather
nonlinear wave in which energy concentrates in a localized and oscillatory fashion
wave
repeated oscillation about a stable equilibrium
