Two closed organ pipes, A and B, have the same length. A is wider than B. They resonate in the fundamental mode at frequencies nA and nB respectively. 

(a) nA = nB 

(b) nA > nB 

(c) nA < nB 

(d) Either (b) or (c) depending on the ratio of their diameters.

Correct Answer is: (c) nA < nB 

Let l = length of pipe, d = diameter of pipe.

In the fundamental mode, λ/4 = l + 0.3d, with end correction.

Frequency = V/λ = V/4(l + 0.3d)

As l is the same, the wider tube will resonate at a lower frequency.
