About WJEC A Level Physics 2.4-2.5 The Nature of Waves and Wave Properties

This topic covers the nature of waves and superposition effects.

What you need to know

  • Wave terms Amplitude, wavelength, frequency, period and phase.
  • Wave equation v = fλ.
  • Interference Path difference and coherence.
  • Double slits and gratings λ = ay/D and dsin θ = nλ.

Common mistakes in 2.4-2.5 The Nature of Waves and Wave Properties

  • Using slit width instead of slit separation.
  • Saying stationary waves transfer energy.
  • Wrong node spacing (half a wavelength).
