Physics Final Exam Flashcards

16304763079	Waves	non-uniform self-sustaining disturbance usually of a material medium that extends over a significant span of space	0
16304805868	Mechanical waves	waves that travel through a medium ex. water waves	1
16304819080	Disturbance	refers to a change away from equilibrium	2
16304828943	Restoring force	this must be present in order for a medium to return to the equilibrium state after being disturbed	3
16304872055	Pascal Law	inc pressure in one direction always implies the same inc in pressure in all directions and everyone in fluid	4
16304897378	Gauge Pressure	Deviation pressure from normal volume changes with pressure	5
16304926521	Incident wave	wave approaching a boundary	6
16304944730	Invert	flip perpendicular to the direction of travel *happens in fixed end	7
16304988108	Upright	the larger displacement remains in the same direction before and after reflection *happens in free end	8
16305102287	Characteristics that distinguish different times of waves	1.Dimensionality 2.Travelling and standing 3.Duration 4.Length	9
16305140990	Traveling waves	if the wave disturbance is confined to a small region of the medium the b/t disturbed and undisturbed medium will move through the medium	10
16305210779	Standing Wave	medium moves in a periodic way the locations of extreme disturbance do not move through the medium	11
16305225130	Transverse Wave	medium motion is perpendicular to the wave motion	12
16305248903	Longitudinal Waves	(compression) medium motion is along the same line as the wave motion	13
16305260107	Wave Pulse	a disturbance that consists of a single bump	14
16305268599	Wave Packets	Consists of more than 1 bump	15
16305277474	Shock Wave	3D traveling compression wave mode of a very short wave packet	16
16309265220	Tension Force	resulting tightness in the string speed of a transverse wave on string	17
16309293961	Nodes	places where medium is never disturbed	18
16309301233	Antinodes	places where the medium is disturbed the most	19
16309376527	Closed tube	fixed displacement end	20
16309382344	open tube	free displacement end	21
16309397566	Consonance	certain pairs of musical pitches sound nicer together	22
16309407343	Dissconant	opp 2 pitches that sound grating together	23
16309440336	Fourier Theorem	any standing wave can be built by superposition from sinusoidal standing wave	24
16309481418	Reeds	narrow rectangles of thin metal spring back to their equilibrium position after being plucked	25
16309503191	Flutes and Reeds are called	woodwinds	26
16309525553	Vibrating energy source	lips, reeds, airstream	27
16309539500	Methods for notes	valve, modes, slides, tone holes	28
16309560308	Resonance	When the driving frequency matches the natural frequency	29
16309571212	Feedback	any situation where the chain of cause and effect circles back on itself	30
16309584336	Response	output of a device system depends only on the input provided	31
16309626748	Register Hole	A hole that can be opened in order to cause an instrument to play in a higher register -possible to force node in middle -open up an octave -place half way of affective length from opening Lower register and upper register	32
16309661746	4 ways to adjust length of instrument	1.don't change the length, but provide a set of tubes with a variety of fixed lengths 2.provide a slide that shortens and lengthens the tube 3.Add valves 4.Add tone holes	33
16309711993	Dispersion	if speed of a wave depends on its shape then the medium is called a dispersive medium 1 consequence: As a traveling wave moves the shape of the disturbance may change	34
16309777468	n is a	whole number	35
16309782584	m is a	half integer	36
16309814923	perfect fifth	3/2	37
16309819882	perfect fourth	4/3	38
16309848929	1.Flute 2.Clarinet 3.Other reeds	1. use n (open tube) 2.use m 3.use n	39
