Review the key ideas from Lessons 1-5, then test yourself with 10 multiple-choice questions and 3 short-answer questions.
Quick Review
Focus: A wave is a disturbance that transfers energy from one place to another. Waves transfer energy, not matter, through a medium or through space.
Key terms: Wave, Energy, Medium
Focus: Transverse waves have vibrations perpendicular to the direction of energy transfer. The direction of particle vibration determines whether a wave is transverse or longitudinal.
Key terms: Transverse wave, Longitudinal wave, Crest
Focus: Amplitude is the maximum displacement from the rest position. Amplitude relates to wave energy, wavelength relates to wave spacing, and frequency relates to how often waves occur.
Key terms: Amplitude, Wavelength, Frequency
Focus: The wave equation is v = f × λ, where v is speed, f is frequency, and λ is wavelength. Rearranging the wave equation allows calculation of any one variable when the other two are known.
Key terms: Wave speed, Wave equation, Frequency
Focus: Review and consolidate your understanding of wave basics, including wave types, amplitude, wavelength, frequency, and wave speed calculations.
