Sketch the three lowest-frequency harmonic wave function patterns for standing waves in the air in a tube that is open at both ends, (a) representing displacement nodes and antinodes and \((b)\) representing pressure nodes and antinodes. Your sketches should be similar to the pattern in Figure \(17.9 \mathrm{c}\).
