Course review
Review each learning objective in this topic, then open its concept explanation or question set.
Learning objective
• Distinguish transverse and longitudinal travelling waves by comparing particle or field oscillation with the direction of propagation and energy transfer. • Describe the motion of particles in a medium using displacement with position and with time.
Start with the concept explanation, then practise to create mastery evidence.
Learning objective
• Apply wavelength λ, frequency f, time period T and wave speed v to wave motion using v=fλ=λ/T.

Learning objective
• Explain sound as a mechanical longitudinal wave, including particle oscillations, compressions and rarefactions, and energy transfer through a medium.
Start with the concept explanation, then practise to create mastery evidence.
Learning objective
• Explain electromagnetic waves as transverse oscillating electric and magnetic fields that can propagate through a vacuum. • Use the approximate wavelength orders of magnitude in the Physics data booklet without treating them as sharp boundaries.
Start with the concept explanation, then practise to create mastery evidence.
Learning objective
• Compare mechanical waves, which require a medium, with electromagnetic waves, which can travel through a vacuum. • Travelling waves transfer energy even when there is no resultant displacement of the medium. • Apply the wave model to both mechanical and electromagnetic waves.
