Chapter 13B 2 Wave Motion Two types of waves: Transverse - the disturbance is perpendicular to the direction of travel Longitudinal - the disturbance is parallel to the direction of travel
Chapter 13B 3 Periodic Waves Many traveling waves are repetitive, or periodic. Periodic waves have a wavelength ( λ ) and a wave speed ( v ). wavelength ( ) wave speed ( v )

Chapter 13B 4 Periodic Waves A fixed point on the medium (string, spring, etc) undergoes up-and-down simple harmonic motion with some frequency ( f ) and period ( T = 1/ f ).
Chapter 13B 5 Equation for Wave Speed How are wave speed, wavelength, frequency, and period related? v = x t In this case: x = λ , t = T , f = 1 T v = f λ
