Two sine waves with the same Amplitude, Wavelength and Frequency travelling in opposite directions will interfere and produce a combined wave . The waveform of the combined waves, on average has No Net Propagation of Energy and is known as standing wave.
Figure 1: Formation of Standing Wave
Property of standing wave:
(1) Nodes: Points which are stationary and with zero amplitude. At nodes, two waves travel in exactly same amplitude and out of phrase offset with each other.
(2) Antinodes: Points at maximum amplitude. At antinodes, two waves travel in exactly same amplitude and in phrase reinforce with each other.
(3) The maximum amplitude of each particle is related with its position and each amplitude oscillates periodically..
Figure 4: Amplitude at different particles of the Standing Wave
(4) The distance between two adjacent nodes or two adjacent antinodes is equal to half of the wavelength.
Figure 5: Distance between nodes or antinodes
(5) As the displacement of the nodes is always zero, the waveform is not travelling. Hence energy is confined between two adjacent nodes.
