The distance from a compression center to the adjacent rarefaction center is 1.5 m.
The given parameters:
The distance from a compression center to the adjacent rarefaction center is calculated as follows;
[tex]d = \frac{\lambda }{2} \\\\d = \frac{3.0}{2} \\\\d = 1.5 \ m \\[/tex]
Thus, the distance from a compression center to the adjacent rarefaction center is 1.5 m.
