Key Topics to Revise

Oscillatory Motion and Simple Pendulum

Oscillatory motion is periodic motion about an equilibrium position
One complete oscillation occurs when the object returns to its starting position in the same direction
Amplitude (a) is the maximum displacement from equilibrium position

Forced Vibration and Resonance

Forced vibration occurs when external vibrating object makes another object vibrate
Resonance happens when natural frequencies of two objects are equal
Objects in resonance vibrate with maximum amplitude

Wave Motion and Types of Waves

Wave motion transfers energy without transferring matter
Waves are classified as mechanical (need medium) and electromagnetic (no medium needed)
Mechanical waves are longitudinal or transverse

Wave Characteristics and Properties

Amplitude determines wave intensity and energy
Wavelength (λ) is distance between consecutive similar points
For longitudinal waves: distance between consecutive compressions or rarefactions
