When one end is closed, n1=(100/2)=50 Hz n2=3n1=150Hz, n3=5n1=250 Hz and so on.

Q. An open organ pipe has a fundamental frequency $100 Hz$ . What frequency will be produced if it's one end is closed?

100,200,300......

50,150,250......

50,100, 200,300....

50,100,150,200......

When one end is closed, $n_{1} = \frac{100}{2} = 50 Hz$
$n_{2} = 3 n_{1} = 150 Hz, n_{3} = 5 n_{1} = 250 Hz$ and so on.
