Question

An organ pipe has geometrical length L, and the end correction for each open end is e. Which pair correctly gives the effective length of an open pipe and a pipe closed at one end?

G1 Physics · Accepted Answer

An open pipe has two open ends, and each contributes one end correction. Therefore, Lₑ(open) = L+2e. A pipe closed at one end has only one open end. Therefore, Lₑ(closed) = L+e. Correct option: B.
