Answer:
The new fundamental frequency will be 3600 Hz.
Explanation:
On a closed organ pipe, the fundamental frequency is given by :
[tex]f=\dfrac{v}{4l}[/tex]
[tex]1800=\dfrac{v}{4l}[/tex].............(1)
l is the length of the pipe
v is the speed of sound
Similarly, on an open pipe the fundamental frequency is given by :
[tex]f'=\dfrac{v}{2l}[/tex]
From equation (1),
[tex]\dfrac{v}{2l}=3600[/tex]
[tex]f'=3600\ Hz[/tex]
So, the new fundamental frequency will be 3600 Hz. Hence, this is the required solution.
