1.	A closed organ pipe of radius r1 and an open organ pipe of radius r2 and having same length L resonate when excited with a given tuning fork. Closed organ pipe resonates in its fundamental mode whereas open organ pipe resonates in its first overtone, then(1) r2 – r1 = L (2) r2 – r1 = L/2(3) r2 – 2r1 = 2.5 L (4) 2r2 – 2r1 = 2.5 L
