Explanation:
the nodes and the antinodes are always located at the same position along the medium; they are standing still. It is this characteristic that has earned the pattern the name standing wave.
If you know the distance between nodes and antinodes, or if you know the length of string (or pipe length) and which harmonic is present. If you know the distance between nodes and antinodes then use this equation: λ2=D. Where D is the distance between adjacent nodes or antinodes.
If you know the frequency and wave speed of the progressive waves that made the standing wave you can use the following equation:
λ=c/f
