Question Answer
soundpassage of disturbance through the air or another medium. vibratory energy transmitted by pressure waves in the air or other media. has potential to do work, does not pass though a vacuum.
wavedisturbance of a medium. particles are temporarily dispalced and then resutrn to their original position.
longitudinal wavesparticles of the medium are displaced in a direction parallel to energy transport (tuning fork)(sound)
transverse wavesparticles of the medium are displaced in a direction perpendicular to the direction of energy transport.
eleasticityrestoring force. ability of an object to return to its initial position.
intertiatendency of a body to remain in motion when in motion and to remain at rest when at rest.
vibrationmovement of an object from one point in space to another point and back again to the first point.
dampingeffect on an objec that reduces the amplitude of oscillation of an object causing the object to come to a stop.
sinusoidal motionvibration of pendulum is aperiodic.
simple harmonic motionperiodic. repeats itself at standard intervals in a specific manner. charcterized by amplitude, period, frequency, phase.
amplitudehow big the motion is. (measured in dB
periodhow long it takes time it takes to complete one cycle. properties of sine wave
frequencynumber of cycles per unit. measures in hertz properties of sine wave
phasedetermines the starting point on the sine wave. defined in degrees of angle 0-360
wavelengthdistance that a sound wave disturbance travels during one complete cycle.
velocityspeed of sound. describes how much the wave travels in a certain amount of time
intantenous amplitudedispalcement of a sine wave varies with time.
peak to peak amplitude from maximum positive peak to the maximum negative peak.
root mean square amplitudesquare root of the average amplitude squared, . 7 time the peak amplitude.
