A cylindrical tube, open at both ends, has a fundamental frequency f0 in air. The tube is dipped vertically into water such that half of its length is inside water. The fundamental frequency of the air column now is

(1) 3 f0/4

(2) f0

(3) f0/2

(4) 2 f0

(2) nopen=v2lopen

nclosed=v4lclosed=v4lopen/2=v2lopen

Aslclosed=lopen2, i.e. frequency remains unchanged.
