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 ?

Text Solution

Verified by Experts

The fundamental 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`
