TPR FL practice test question (chem section) gives a question asking what happens at the end of an open air column in an instrument.
Without any background knowledge from the passage, I assume that closed ends have nodes because air is not moving at that point and antinodes at open ends because the wave can expand at that point.
Apparently this is backwards and upon rereading the appropriate part of the passage I see that they do mention this. Any input on whether I'm totally wrong or...
