Tube A has both ends open, while tube B has one end closed, otherwise they are identical the ratio of fundamental frequency of tubes A & B?

Tube A has both ends open, while tube B has one end closed, otherwise

1.	Tube A has both ends open, while tube B has one end closed, otherwise they are identical the ratio of fundamental frequency of tubes A & B?
Answer» Solution :The fundamental frequency for tube A with both into OPEN is `V_(B) = V/(2L)` The fundamental frequency for tube B WIT ONE end closed is `V_(B) = V/(4L) , (VA)/(VB) = (V//2L)/(V//4L) =2`
