1. Use the data that you have for the air-filled tube.
• Make a drawing of the standing wave in the tube when you have two, three, and four nodes or peaks. These will correspond to the first, second, and third overtones.
• For each standing wave, label the nodes and the antinodes.
• Label and record the distance in meters of the half wavelength (λ/2) for each standing wave.
• Explain how the standing wave occurs.
