Oscillation and waves

Oscillations and Waves: Free Oscillations: Basics of SHM, derivation of the differential equation for SHM, Mechanical simple harmonic oscillators (spring constant by series and parallel combination), Equation of motion for free oscillations, Natural frequency of oscillations. Damped Oscillations: Theory of damped oscillations (derivation), over damping, critical & under damping (only graphical representation), quality factor. ForcedOscillations: Theory of forced oscillations (derivation) and resonance, sharpness of resonance. Shock waves: Mach number, Properties of Shock waves, Construction and working of Reddy shock tube, applications of shock waves, Numerical problems.
