Key Topics to Revise
Introduction to Waves
- Waves are patterns that move without physical transfer of matter
- Energy and information propagate through waves
- Example: When a pebble is dropped in water, circles move outward but water doesn't flow away from center
Transverse and Longitudinal Waves
- Classification based on direction of particle oscillation relative to wave propagation
- Transverse waves: particles oscillate perpendicular to wave direction
- Examples of transverse waves: waves on string, water surface waves
Wave Equation and Properties
- Mathematical description requires function of both position x and time t
- Sinusoidal waves are most common and important
- Wave function describes shape at any instant and motion at any location
Wave Speed
- Wave speed depends only on properties of the medium, not on frequency
- Speed is constant for given medium and wave type
- Different types of waves have different speeds in same medium
