Waves: V = λf, Velocity of a Wave, Graphs: Displacement-Distance & Displacement-Time - IB Physics

I show several animations proving that the velocity of a wave is wavelength x frequency, create a displacement-distance graph and a displacement-time graph of a wave and discuss the information you can get from both, and use both types of graphs to solve for the velocity of a wave.
