PHY 122013 Term 1Week 1:Wave Properties and EquationsWhat is a wave?General definitions of vibrations and wavesVIBRATION OF A PENDULUMTl g 2nWhat does the period(T)depend upon?uLength of the pendulum(l).uAcceleration due to gravity(g).nPeriod does not depend upon the bob mass or the amplitude of the swing.Vibration of a pendulum.The to-and-fro vibratory motion is also called oscillatory motion(or oscillation).nWhen oscillations are small,the motion is called simple harmonic motion(shm)and can be described by a simple sine curve.Crests and TroughsWave PropertiesAmplitudeAMPLITUDE(A)Wave PropertiesWavelengthWavelength()Wave PropertiesFrequencyFrequency(f)Wave PropertiesPeriodPeriod(T)Examples of FrequencyfT1Relationship between T and fPutting everything togetherThinkThinkThinkWave Motion,Speed,Type 12/18/2022The Wave Equation12/18/2022Some example wave equation questionsWave Types12/18/2022Transverse vs.longitudinal wavesSound WavesMolecules in the air vibrate about some average position creating the compressions and rarefactions.We call the frequency of sound the pitch.SUMMARYHomeworknNCSP Textbook Problems:13.1-13.5,16.1-16.4n Gardiner:Set 30,33
