Question

the tuning fork is kept in vertical plane or horizontal plane in resonance column tube experiment​

Answer 1

Answer:

In an experiment to determine the speed of sound using a resonance column , prongs of the tuning fork are kept in a vertical plane so that both the prongs can send sound waves inside the tube .

In one resonance the length of resonating air column is ,

l

1

=λ/4 ,

and in another resonance the length of resonating air column is ,

l

2

=3λ/4 ,
