2. Activity-Based QuestionsIn the activities that follow we would like you to determine the speed of the transverse wave andcompare it to the theoretical prediction of the wave speed as a function of the Slinky tension,Tand its mass per unit length (or linear density),µ. Finally you will measure the speed of thelongitudinal wave.(a) Open the LoggerProfile <WaveSpeed_T.cmbl> and use video analysis to determine thespeed of propagation of the transverse wave crest in m/s using the <SlinkyWave_T10(hi-speed).mov>. Explain your procedure and report your results rounded up to 3 significantfigures along with the uncertainty (RSME).Note: Don’t forget to scale the movie verycarefully using theSet Scaletool (you can repeat the scaling until the green line looks justright). Then move ahead to the first frame that shows the wave crest. You may want to useeither theCurve FitorModel. . .feature in theAnalysismenu to determine the velocity.,m/s
(b)Calculate the theoretical speed of a transverse wave:A derivation in most introductoryphysics texts predicts that the equation for the wave speed of a small amplitude transversewave on a spring or string of should bevwT whereTis the tension in the spring and  is itsmass per unit length (or linear density).Note: If you predicted in 1(b) and 1(c) that speedshould increase with tension and decrease with mass per unit length (i.e., linear density), thenthe equation for speed is consistent with that prediction.TheTand  data for the Slinky, as shown on the title screen of the transverse wave movie entitled<SlinkyWave_T01(hi-speed).mov>, is given asT = 1.7 N& = 0.081 kg/mDetermine the theoretical value of the wave speed for the transverse wave to three significantfigures and show your calculations.
