A certain organ pipe is open at both ends. Another pipe of the same length is open at one end and closed at the other. Which will have the lower pitch?
A) The pipe open at both ends.
B) The pipe closed at one end.
C) Both will have the same pitch.
D) It depends on the pipes' diameters.

Question

The pipe closed at one end will have a lower pitch because it can only support odd harmonics due to its boundary conditions, leading to a lower fundamental frequency compared to the pipe open at both ends, which supports both even and odd harmonics.
