A) The wavelength is 4L and there is a displacement node at the pipe's open end.
B) The wavelength is 4L and there is a displacement antinode at the pipe's open end.
C) The wavelength is L and there is a displacement node at the pipe's open end.
D) The wavelength is L and there is a displacement antinode at the pipe's open end.
