Two organ pipes have identical lengths. One is open at both ends, and the other is closed at one end. Which statement best describes the relationship between their fundamental frequencies?
(a) The closed pipe’s fundamental frequency is equal to that of the open pipe.
(b) The closed pipe’s fundamental frequency is 21 that of the open pipe.
(c) The closed pipe’s fundamental frequency is 2 times that of the open pipe.
(d) The closed pipe’s fundamental frequency is 23 times that of the open pipe.
