value above or below the equilibrium value
distance between two successive crests (or troughs)
how often vibrations or waves occur per unit time; often expressed as Hertz (Hz), meaning waves/sec or cycles/sec.
time for a single wave or vibration
the speed and direction of a wave
Velocity of a wave= wavelength x frequency
a pictorial representation of a wave
the unit of frequency, equal to one cycle per second
a cone shaped wave produced by an object moving at supersonic speed through a fluid
A pattern formed by the overlapping of two or more waves that arrive in a region at the same time.
the speed at which a wave travels
The explosive sound heard when a shock wave from an object traveling faster than the speed of sound reaches a person's ears
A wave that moves the medium in a direction perpendicular to the direction in which the wave travels
a pattern of vibration that simulates a wave that is standing still
The V-shaped wave produced by an object moving on a liquid surface faster than the wave speed.
A wave in which the vibration of the medium is parallel to the direction the wave travels
An observed change in the frequency of a wave when the source or observer is moving
