A cylindrical tube open at both ends, has a fundamental frequency `f`

1.	A cylindrical tube open at both ends, has a fundamental frequency `f` in air. The tube is dipped vertically in air. The tube is dipped vertically in water so that half of it is in water. The fundamental frequency of the air column is nowA. `v//2`B. `v`C. `3 v//4`D. ` 2 v`
Answer» Correct Answer - B `f_(open) = (v)/( 2l) = v` `f_(closed) = (v)/(4 ((l)/(2))) = (v)/( 2l) = v`
