1.	In a resonance-column experiment, the tuning fork is held above the open end of the glass tube. This can be done in two ways: position (1) one prong above the other, and position (2) the two prongs at the same horizontal level. The correct position is (a) (1) in all cases (b) (2) in all cases (c) (1) for first resonance and (2) for second resonance (d) (2) for first resonance and (1) for second resonance
Answer» Correct Answer is: (a) (1) in all cases Most of the sound emitted by a tuning fork is propagated in the plane in which the prongs lie. Here, the sound has to be directed into the tube.
