Oscillations and Waves

This chapter explains the concepts of periodic, oscillatory and simple harmonic motions by discussing velocity, acceleration, force law and energy in harmonic motions. It also explains the damped and forced oscillations with the concept of resonance.

This chapter explains the concepts of transverse and longitudinal waves through displacement relations, speed, reflection and the principle of superposition of the waves. It also discusses the concept of the Doppler effect with its significance.
