IB Physics HL C.2.4 Transverse & longitudinal waves
Practise reading wave diagrams to distinguish transverse and longitudinal motion, predict particle movement, and compare sound and light in vacuum.
How this is tested
- use a wave diagram to decide propagation direction and predict whether a marked point moves up or down next
- state from a wave diagram that transverse displacement is perpendicular to the propagation direction
- choose between sound and light by deciding wave type and whether each can travel through vacuum
