When an open organ is dipped in water upto half of its height, then its frequency will become

organ pipe - Sound producing such a tube which is close at one end and open at other end is called closed organ pipe, and the tube which open at both the ends called open organ pipe.
Frequency of open organ pipe is double than that of closed pipe.
If frequency of open pipe = n
∴ Frequency of closed pipe =
On inserting an open pipe into water upto half of its height, it will behave like a closed pipe of half length and frequency is inversely proportional to the length of air column.
Hence, frequency of closed pipe will become double
= 2 ×
= n
