1. Wave Nature
A wave is a disturbance that transfers energy through a medium. Transverse waves (vibration perpendicular to motion) and Longitudinal waves (vibration parallel to motion).
2. Key Characteristics
- Frequency (f): Number of cycles per second (Hertz).
- Wavelength (λ): Distance between consecutive peaks.
- Wave Speed: v = fλ.
3. Doppler Effect
The change in frequency of a wave in relation to an observer who is moving relative to the wave source.
