Answer
In the second harmonic of a stationary wave in a pipe open at both ends, there are antinodes located at each end of the pipe. This indicates that maximum displacement occurs at both ends.
Step 2
One full wave shown (i.e. antinode-node-antinode)

Answer
In the diagram, there should be one complete wave represented, consisting of an antinode at one end, a node in the middle, and another antinode at the opposite end. This forms a complete sine wave shape within the length of the pipe.
