vibration: an oscillation of the parts of a fluid or an elastic solid whose equilibrium has been disturbed, or of an electromagnetic wave.
wave: a long body of water curling into an arched form and breaking on the shore
wave period: Frequency is the number of occurrences of a repeating event per unit time. It is also referred to as temporal frequency, which emphasizes the contrast to spatial frequency and angular frequency.
crests: reach the top of (something such as a hill or wave).
troughs:a channel used to convey a liquid.
amplitude: the maximum extent of a vibration or oscillation, measured from the position of equilibrium.
wavelength: the distance between successive crests of a wave, especially points in a sound wave or electromagnetic wave.
frequency:
the rate at which a vibration occurs that constitutes a wave, either in a material (as in sound waves), or in an electromagnetic field (as in radio waves and light), usually measured per second.
hertz: the SI unit of frequency, equal to one cycle per second.
transverse waves: a wave vibrating at right angles to the direction of its propagation.
longitudinal waves: a wave vibrating in the direction of propagation.
wave period: (or decrease) in the frequency of sound, light, or other waves as the source and observer move toward (or away from) each other. The effect causes the sudden change in pitch noticeable in a passing siren, as well as the redshift seen by astronomers.
blue shift: the displacement of the spectrum to shorter wavelengths in the light coming from distant celestial objects moving toward the observer.
red shift: the displacement of spectral lines toward longer wavelengths (the red end of the spectrum) in radiation from distant galaxies and celestial objects. This is interpreted as a Doppler shift that is proportional to the velocity of recession and thus to distance.
shock wave: a sharp change of pressure in a narrow region traveling through a medium, especially air, caused by explosion or by a body moving faster than sound.
sonic boom: a loud explosive noise caused by the shock wave from an aircraft traveling faster than the speed of sound.
