Question1
Consider a tube filled with air (at 17 °C) and closed at both ends. Let length of the tube is 70 cm.
(a) what is fundamental (lowest) resonance frequency in this tube?
(b) Illustrate the node-antinode pattern of the next 2 higher resonant frequencies. What is the value of those frequencies?
(c) If one end is now opened (the other end is still closed), what will be fundamental resonance frequency
