1.	A cylindrical tube, open at both ends has a fundamental frequency f 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 now …………. .
Answer» F/2 4 3f/4 2f Solution :When the tube is dipped in water , it BECOME a CLOSED pipe of LENGTH L/2 . Its FUNDAMENTAL frequency is`f. = (v)/(4(L//2)) = f`
