The closed and open organ pipes have same length. When they are vibrating simultaneously in first overtone, they produce four beats. The length of open pipe is made half and that of the closed pipe is made two times the original. Now the number of beats produced if the two pipes are vibrating in their fundamental modes simultaneously is
- A 8
- B 10
- C 14
- D 16
Answer & Solution
Correct Answer
(C) 14
