7C: Tube A is an open-close tube of 2m length. Find its fundamental frequency f₁. Tube B is an open- open tube that is 4m long. I want to cut tube B so that when tube A and B vibrate at their respective fundamental frequencies, then beats of 5Hz are heard. What should I make the length of tube B? Take the speed of sound = 340 m/s. LB =
