Revise Edexcel GCSE Physics 4.1.4 The wave speed equations with the question bank and revision guides.
Recall and use both the equations below for all waves: wave speed (metre/second, m/s) = frequency (hertz, Hz) × wavelength (metre, m), v = f × λ; wave speed (metre/second, m/s) = distance (metre, m) ÷ time (second, s), v = x ÷ t.
