Model No: AGN-1223
It is designed to study the resonance of air columns in a laboratory setup. It consists of a heavy-duty stainless-steel tube (S.W.G. No. 16) mounted alongside a meter scale on a polished wooden board. The lower end of the tube is sealed into a metal cup connected via rubber tubing to a brass reservoir, allowing precise adjustment of the air column length. The apparatus enables accurate measurement of resonance conditions for sound experiments.
