1.	Tube A has both ends open, while B has on end closed otherwise the two tubes are identical. What is the ratio of fundamental frequency of the tubes A and B ?
Answer» SOLUTION :Thefundamental frequency for tube A with both ends open is `f_A = V/(2L)` The fundamental frequency for tube B with ONE end closed is `f_B = v/(4L)` `f_A/f_B = (v//2L)/(v//4L) =2 RARR f_A : f_B = 2 : 1`
