An air column in a pipe closed at one end is made to vibrate in its second overtone by a tuning fork of frequency 440 Hz The speed of sound wave in air is 330 m s End corrections may be neglected Let P denote the mean pressure at any point in the pipe and AP the maximum amplitude of pressure variation Then 15 A length of the pipe is m 16 9 B length of the pipe is m 16 0 C the maximum pressure at the open end is Po D the minimum pressure at the open end is P
