Question: 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
[UPSEAT 2001]
Options:
A) 17, closed
B) 85, closed
C) 17, open
D) 85, open
Show Answer
Answer:
Correct Answer: B
Solution:
Let the base frequency be n for closed pipe then notes are $ n,\ 3n,\ 5n…..
$ note $ 3n=255 $
Therefore $ n=85 $ , note $ 5n=85\times 5=425 $ note $ 7n=7\times 85=595 $
