IIT-JEE/AIEEE Physics:Waves and Oscillations Part II

Description
This lecture basically deals with Damped Oscillations. It starts with beats. Excellent experiments on beats are worth seeing.The mathematical treatment is slightly different in the sense that it uses complex numbers to express the simple harmonic function.Damping in electrical circuits,Q-factor are some other topics which are discussed. Don't miss the experiment showing damped motion at the end of the lecture.The credit for the video goes to Youtube.com.
