Stationary Wave Questions: Can Open Tubes Produce Them?

[momomo_mo]

Questions again!
AS I know stationary can be produced by the reflection of waves in a closed tube.But how can stationary still be produced in an open tube??


Thanks for your help

Think in terms of air pressure. What is the air pressure likely to be at the open ends of the tube? What is it likely to be at the centre of the tube?

Yes, open tubes can also produce stationary waves. This is because the standing wave pattern is formed by the interference of the incoming and reflected waves, regardless of whether the tube is open or closed at one end. In an open tube, the reflected wave may not be completely inverted, but it can still interfere with the incoming wave to create a stationary wave pattern. This phenomenon is observed in musical instruments such as flutes and clarinets, which have open tubes. I hope this helps answer your question!
