25.3 Wave Motion
25.4 Wave Speed
- Define three terms to describe periodic waves: wave
speed, wavelength and frequency.
25.5 Transverse Waves
25.6 Longitudinal Waves
- Explain the characteristics of transverse, longitudinal and
surface waves.
25.7 Interference
- Understand how the principle of superposition is applied
when two pulses meet.
25.8 Standing Waves
- Describe the formation of standing waves.
- Apply the principle of superposition to the phenomenon
of interference.
- Calculate the fundamental frequency and the overtones.
- Understand how resonance occurs.
25.9 Doppler Effect
- Apply the Doppler Effect principle to problems involving
moving sources or moving listeners.
