3.1 — General properties of waves

Core

3.1.1 — Know that waves transfer energy without transferring matter
3.1.2 — Describe wave motion as illustrated by vibrations in ropes, springs and water waves
3.1.3 — Describe wavefront, wavelength, frequency, crest, trough, amplitude and wave speed
3.1.4 — Recall and use the equation v = fλ
3.1.5 — Know that transverse waves vibrate at right angles to direction of propagation; electromagnetic radiation, water waves and S-waves can be modelled as transverse
3.1.6 — Know that longitudinal waves vibrate parallel to direction of propagation; sound waves and P-waves can be modelled as longitudinal
3.1.7 — Describe reflection, refraction and diffraction of waves
3.1.8 — Describe the use of a ripple tank to show reflection, refraction (by depth change), diffraction through gaps and past edges

3.1.9 — Describe how wavelength and gap size affect diffraction through a gap
3.1.10 — Describe how wavelength affects diffraction at an edge
