Distance between any two consecutive identical points along a wave; distance interval for wave repitition. what is amplitude? 1/2 of crest to trough distance.maximum displacement for equilibrium on either side. What is a crest? Point of maximum positive displacement. a+ peak. what is a trough? a maximum negative displacement; a - peak what is Equilibrium? Point (or line) of Zero displacement; undisturbed position. What is a Cycle? One complete vibration or Oscillation.The distance measured from crest to crest. What is a Period? The time it takes for one wave to repeat itself.Time / # of Cycles What is Frequency? # of Cycles/ time A moving distrubance requiring a material medium to move in it is called Machanical Wave A wave in whcih the medium vibrates parallel to the direction of wave travel is a Longitudinal wave As a mechanical wave travels, it transfers an amount of------ related to the waves amplitude. energy Frequency has a SI unit of Hz (or s-1) What does SHM stand for? Simple Harmonic Motion At a constant speed, if the wavelength increases, then the frequency of the wave must decrease if the wavelength increases, then the speed of the wave must... stay constant the relationship between wavelenth and frequency is a(n) inverse relationship The speed of an mechanical wave can be varied only by changing the medium. If a wave propigates at one cycle every 1 second, then it has a ____ of 1s. period Period is defined as time for one cycle This is not an example of SHM a record rotation on a turntable.. this is an example of SHM a child swinging on a swing. amplitude is defined as the maximum displacement from equilibrium For SHM where do the force and acceleration have maximum magnitude? At the crest and the trough of a wave. For SHM where does maximum velocity occur? At equilibrium .remove_background_ad { border: 1px solid #555555; padding: .75em; margin: .75em; background-color: #e7e7e7; } .rmbg_image { max-height: 80px; } Authorbailesxlove11 ID67888 Card SetPhysics DescriptionSHM and waves Updated2011-02-21T19:40:14Z Show Answers
