Question | Answer |
---|---|
a oscillation, or repeating back and forth motion, about an equillibrium position | vibration |
a disturbance that repeats regularly in space and time and that is transmitted progessively from one place to the next with no actual transport of matter. | wave |
the time required for a pendulum to make one to and from swing. in general, the time required to complete a sinle cycle. | period |
the back and forth motion vibratory motion of a swinging pendulum | simple harmonic motion |
a curve whose shape represents the crests and troughs of a wave, as traced out by a swinging pendulum that drops a trail of sand over a moving conveyor belt. | sine curve |
one of the places in a wave where the wave is highest or the disturbance is greatest. | crest |
one of the places in a wave where the wave is the lowest, or the disturbance is greatest, in the opposite direction from a crest. | trough |
the distance from the midpoint to the maximum (crest) of a wave or, equivalently, from the midpoint to the minimum (trough). | amplitude |
the distance from the top of the crest of a wave to the top of the following crest, or equivalently, the distance between successive identical parts of the wave. | wavelength |
the number of events (cycles, vibrations, oscilliations, or any repeated event) per time; measured in hertz (or events per time.) inverse period. | frequency |
the SI unit of frequency. one hertz is one cycle per second | hertz |
a wave with the vibration at right angles to the direction the wave is traveling. | transverse wave |
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. | longitudinal wave |
a pattern formed by the pverlapping of two or more waves that arrive in a region at the same time. | interference pattern |
