|an oscillation, or repeating back-and-forth motion, about an equilibrium position is...
|a disturbance that repeats regularly in space and time and that is transmitted progressively from one place to the next with no actual transport of matter is...
|the time required to complete a single cycle is...
|simple harmonic motion
|the back-and-forth vibratory motion of a swinging pendulum is...
|a curve whose shape repeats the crests and troughs of a wave is...
|one of the places in a wave where the wave is the lowest, or the disturbance is the greatest is...
|the distance from the midpoint to the crest of the wave (and vice versa) is...
|the distance from the top of the crest of a wave to the top of the following crest (or trough) is...
|the number of events (cycles, vibrations, oscillations) per time
|the SI unit of frequency, one Hz=w/s
|a wave with vibration at right angles to the direction the wave is traveling
|a wave in which the vibration is in the same direction as that which the wave is traveling
|a pattern formed by the overlapping of 2 or more waves that arrive in a region at the same time
|addition of 2 or more waves when crests overlap to produce a resulting wave of increased amplitude
|combination of waves where crests of one wave overlap troughs of another, resulting in a wave of decreased amplitude
|out of phase
|term applied to 2 waves for which the crest of one wave arrives at a point at the same time that a trough of the second wave arrives. their effects cancel each other out.
|term applied to 2 or more waves whose crests and troughs arrive at a place at the same time so that their effects reinforce each other.
|wave in which parts of the wave remain stationary and the wave appears not to be traveling. The result of interference between an incident wave and a reflected wave
|any part of a standing wave that remains stationary.
|the positions on a stationary was where the largest amplitudes occur.
|the apparent change in frequency of a wave due to the motion of the source of of the receiver
|an increase in the measured frequency of light from an approaching source; called the blue shift because the apparent increase is toward the high frequency (blue) end of the spectrum.
|a decrease in the measured frequency of light from a receding source; called red shift because the decrease is toward the low frequency (red) end of the spectrum.
|the V-shaped wave produced by an object moving on a liquid surface faster than the wave speed.
|a cone shaped wave produced by an object moving at supersonic speed through a fluid.
|the sharp crack heard when the shock eave that sweeps behind a supersonic aircraft reaches the listener.
