1.	In a resonance column experiment , the first resonance is obtained when the level of the water in the tube is at `20 cm` from the open end . Resonance will also be obtained when the water level is at a distance ofA. `40 cm` from the open endB. `60 cm` from the open endC. `80 cm` from the open endD. `100 cm` from the open end
Answer» Correct Answer - B For second resonance `L_(2) = ( 3lambda)/(4) = 3L_(1) = 3 xx 20 = 60 cm`
