2 1 Important Points from last Lecture Simple Harmonic Oscillator is a consequence of The Period T is Pendulum: Damped Oscillations: F k x T 2 m k , f 1 T 1 2 k m T 2 l g , f 1 T 1 2 g l Shock absorbers: 1 Waves Waves are “ moving oscillations ”. They carry energy ; they do NOT carry matter (Think of water waves) Wavelength , l : length of one full cycle at fixed time Period , T : time for one full cycle at fixed position Waves travel at speed v v T v position T v
3 1 Waves 2 Waves are “ moving oscillations ”. The time-period T of the wave and the space-period ? of the wave are connected by the wave speed v; v position v T v f f v T v 1 Energy Transport in Waves We define Intensity of wave as the power transported through unit area . the energy of the wave is proportional to Amplitude 2 .
