The experiment was about creating a sound wave inside a close ended resonance tube and finding the locations of maximum and minimum amplitude. (after adjusting the tube length that makes a standing wave). The experiment used an oscilloscope and at the closed end there was a maximum amplitude. Why would this happen? Something wrong with the setup?
Is is possible for a closed ended tube to have an anti-node instead of a node?
The speaker is at the left end side and the right side is the close end. The mic (the device inside the tube with the wire attached) measures the amplitude of the standing wave. The mic is right next to the close end. The function at the top is the input sound wave and the bottom function is the amplitude of the standing wave at the location (where mic is at).
