Know: waves transfer energy without transferring matter
3.1.2—What is meant by wave motion as
Describe what is meant by wave motion as illustrated by vibrations in ropes and springs, and by experiments using water waves
3.1.3—Features of a wave in terms of
Describe the features of a wave in terms of wavefront, wavelength, frequency, crest (peak), trough, amplitude and wave speed
3.1.4—Recall/use: for wave speed v = f λ
Recall/use: for wave speed v = f λ
3.1.5—For a transverse wave, the direction
Know: for a transverse wave, the direction of vibration is at right angles to the direction of propagation and understand that electromagnetic radiation, water waves and seismic S-waves (secondary) can be modelled as transverse
3.1.6—For a longitudinal wave, the direction
Know: for a longitudinal wave, the direction of vibration is parallel to the direction of propagation and understand that sound waves and seismic P-waves (primary) can be modelled as longitudinal
3.1.7—Waves can undergo: (a) reflection at a
Describe how waves can undergo: (a) reflection at a plane surface (b) refraction due to a change of speed (c) diffraction through a narrow gap
3.1.8—Use of a ripple tank to show: (a)
Describe the use of a ripple tank to show: (a) reflection at a plane surface (b) refraction due to a change in speed caused by a change in depth (c) diffraction due to a gap (d) diffraction due to an edge
