|The weight attached to a string that is free to move back and forth in a fixed position.
|The distance from the midpoint to the maximum of a wave or, equivalently from the midpoint to the minimum.
|The time required for a pendulum to make one to-and-fro swing. In general, the time to complete a single cycle.
|A curve whose shape represents the crest and troughs of a wave, as traced out by a swinging pendulum that drops a trail of sand over a moving conveyor belt.
|simple harmonic motion
|Periiodic motion in which acceleration is proportional to the distance from an equilibrium position and is directed toward that equlibriium position.
|One of the places on a wave where the wave is lowest or the disturbance is greatest, in the opposite direction from the crest.
|One of the places in a wave where the wave is highest or the disturbance is greatest.
|A "wiggle" in space and time, 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.
|An oscillation, or repeating back and forth motion, about equilibrium position.
|the distance from the top of the crest of one wave to the top of the following crest, or equivalents, the distance between two successive parts of a wave
|a wave with vibration at right angles jto the direction the wave is traveling
|A wave in which the vibration is in the same direction as that in which the wave is traveling rather than at right angles to it.
|A pattern formed by the overlapping of two or more waves that arrive in a region at the same time.
|addition of two or more waves when wave crests overlap to produce a resulting wave of increased amplitude.
|combination of waves where crusts of one wave overlap troughs of another, resulting in a wave of decreased amplitude
|out of phase
|term applied to two waves for which the crest of one wave arrives at the point at the same time that a trough of the second wave arrives. Their effects cancel each other.
|term applied to two or more waves whose crests (and troughs) arrive at a place the same time so that their effects reinforce each other
|wave in which parts of the wave remain stationary and the wave appear not to be traveling. The result of the interference between an incident (orginal) wave and a reflected wave.
|any part of a standing waves that remains stationary
|the positions on a standing wave whre the largest amplitude occur
|the change in frequency of a wave due to the motion of the source of the receiver
|an increase in the measured frequency of light from an approaching source; it is called this because the apparent increase i twoard the high frequency end of the color spectrum; also occurs when an observer approaches a source
|a decrease in a measured frequency of light (or other radiation) because the decrease is toward the low-frequency or red end of the color spectrum
|faster than sound
|the V-shaped wave produced by an object moving on a liquid surface than the wave's speed
|a cone shaped wave produced by an object moving at supersonic speed through a fluid
|the sharp crack heard when the schock wave that sweeps behind a supersonic aircraft reaches the listener
