Vibrations and Waves Vocab Quiz Review

an oscillation, or repeating back-and-forth motion, about an equilibrium position

• vibration

• wave

• simple harmonic motion

• wavelength

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

• longitudinal wave

• vibration

• period

• wave

the time required for a pendulum to make one to-and-fro swing. In general, the time required to complete a swing cycle

• period

• frequency

• in phase

• node

the back and forth vibratory motion of a swinging pendulum

• vibration

• wave

• sine wave

• simple harmonic motion

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

• transverse wave

• sine wave

• longitudinal wave

• standing wave

one of the places in a wave where the wave is highest or the disturbance is the greatest. Highest point of a transverse wave

• crest

• trough

• node

• in phase

one of the places in a wave where the wave is lowest or the disturbance is the greatest in the opposite direction from a crest. lowest point of a transverse wave

• out of phase

• trough

• destructive interference

• doppler effect

the distance from the midpoint to the maximum (crest) of a wave, or equivalently, from the midpoint to the minimum (trough)

• node

• shock wave

• amplitude

• wavelength

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

• sonic boom

• amplitude

• wavelength

• frequency

The number of events(cycles, vibrations, oscillations, or any repeated event) per time; measured in hertz(or events per time). Inverse of period.

• period

• frequency

• wavelength

• antinode
