Waves Flashcards

16311683546	A Wave	is a disturbance that transfers energy from place to place	0
16311683547	Vibration	A repeated back and forth or up and down motion.	1
16311683548	Medium	The material through which a wave travels is called a Gases (air), liquids, solids	2
16311683549	Mechanical Waves	Waves that REQUIRE a MEDIUM to transfer energy.	3
16311683550	Electromagnetic waves	Waves that can travel and transfer energy WITHOUT a medium.	4
16311683551	Perpendicular	2 lines that cross at a right angle (90 degrees)	5
16311683552	Transverse Waves	Waves that move the medium at right angles (perpendicular) to the direction in which the waves travel	6
16311683553	Crest	The high part of a transverse wave	7
16311683554	Trough	The low part of a transverse wave is called a	8
16311683555	Longitudinal waves	Waves move the medium parallel to the direction in which the waves travel.	9
16311683556	Parallel	2 lines that will never cross.	10
16311683557	Compression	Area of longitudinal wave where the coils are close together	11
16311683558	Rarefaction	Area of longitudinal wave where the coils are spread out, or rarefied	12
16311683559	Amplitude	the maximum distance the particles of the medium carrying a wave move away from their rest position.	13
16311683560	Wavelength	the distance between two corresponding parts of a wave.	14
16311683561	Frequency	the number of complete waves that pass a given point in a certain amount of time.	15
16311683562	Speed	how far the wave travels in one unit of time.	16
16311683563	Amplitude (Measure)	Measure rest to crest OR rest to trough	17
16311683564	Wavelength (Measure)	Measure starting point to starting point, crest to crest, OR trough to trough.	18
16311683565	Frequency (Measure)	Count number of waves and divide it by seconds.	19
16311683566	Wave Speed (Measure)	Frequency x wavelength units: cm/sec or mm/sec	20
16311683567	Sound	a longitudinal wave	21
