What is the base frequency if a pipe gives notes of frequencies 425, 255 and 595 and decide whether it is closed at one end or open at both ends
17, closed
85, closed
17, open
85, open
Let the base frequency be n for closed pipe then notes are n, 3n, 5n.....∴ note 3n=255⇒n=85 , note 5n=85×5=425note 7n=7×85=595
