Physics chap 8 (Elasticity and Waves)

loading
The maximum displacement of the medium through which the wae travels from equilibrium?
THE AMPLITUDE "A" OF A WAVE
Motion within the wave is parallel to the direction of motion of the wave itself?
LONGITUDINAL WAVE
Motion within the wave is perpendicular to the direction of motion of the wave itself?
TRANSVERSE WAVE
T or F

Vibrations are the result of the elastic properties of substanes, which cause them to return to their original configurations when deformed?
TRUE
Motion that is repeated over and over again?
PERIODIC MOTION
The organized vibration of air molecules due to some source of vibration?
SOUND WAVE
Change in the observed frequency of a wave depending upon the relative motion of the source and observer?
DOPPLER EFFECT
The lowest frequency at which an object will vibrate?
FUNDAMENTAL FREQUENCY
The forced vibration of an object by a wave having the natural frequency of the object?
RESONANCE
What happens when two waves of nearly equal frequency are combined?
A phenomenon called BEAT results.
The process by which waves produce a smaller disturbance?
DESTRUCTIVE INTERFERENCE
The process by which added waves produce a larger disturbance?
CONSTRUCTIVE INTERFERENCE
This is used to gauge the sound level relative to some standard, rather than in terms of power per unit area?
THE DECIBEL SCALE
The energy it carries per unit time per unit area?
THE INTENSITY OF A WAVE
