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 wave can be described as a disturbance that travels through a medium from one location to another location.
Wave period: The time in seconds between successive wave crests as they pass a stationary point on the ocean surface, such as a buoy.
Crests: A crest is the point on a wave with the maximum value or upward displacement within a cycle
Troughs: one o the places in a wave where the wave is the lowest, ot the disturbance is greatest, in the oppisite direction from a crest.
Amplitude: the maximum displacement or distance moved by a point on a vibrating body or wave measured from its equilibrium position.
Wavelength: the distance, measured in the direction of propagation of a wave, between two successive points in the wave that are characterized by the same phase of oscillation.
Frequency: the number of periods or regularly occurring events of any given kind in unit of time, usually in one second.
Hertz: the standard unit of frequency in the International System of Units (SI), equal to one cycle per second.
Transverse waves: a wave in which the direction of displacement is perpendicular to the direction of propagation, as a surface wave of water.
longitudinal waves: a wave in which the direction of displacement is the same as the direction of propagation, as a sound wave.
Doppler Effect:
the shift in frequency (Doppler shift) of acoustic or electromagnetic radiation emitted by a source moving relative to an observer as perceived by the observer: the shift is to higher frequencies when the source approaches and to lower frequencies when it recedes.

Blue shift:
a shift toward shorter wavelengths of the spectral lines of a celestial object, caused by the motion of the object toward the

Red Shift : a shift toward longer wavelengths of the spectral lines emitted by a celestial object that is caused by the object moving away from the earth.
Shock wave:
a repercussion from a startling event or upheaval; series of aftereffects: shock waves from the recent collapse of one of the nation's largest banks.

Sonic boom:
a loud noise caused by the shock wave generated by an aircraft moving at supersonic speed.
