- Recall that impedance for air in a confined space is inversely
proportional to it's area (the smaller the area, the larger the
impedance).
- For a tube open at one end
- assume the wave impedance of open air is negligible to that of the tube cylindrical
section:
- the reflection coefficient for pressure at an open end is
- For a tube closed at one end
- assume an infinitely small radius and a corresponding wave impedance
that is very large relative to
