Stationary Waves – waveforms created through superimposing two identical progressive waves moving in opposite directions (incident and reflected). As they pass over each other, constructive and destructive interference occurs resulting in positions of maximum particle displacement (antinode) and constant zero displacement (node).
Amplitude of Stationary Waves vary with position (0 at nodes)
All particles between two successive nodes have the same phase
Particles on either side of a node or antinode are 180° out of phase
Does not transfer energy but there is energy in the waveform
All particles have the same frequency except for the nodes
