Resonance Apparatus
Product Code : EL-PLE-16323
Eduscope India is a leading Resonance Apparatus
Quick Answer: The Resonance Apparatus is used to locate resonance positions in an air column, from which the speed of sound can be calculated using the water level and the frequency of a tuning fork, making it valuable physics lab equipment India schools and colleges rely on for sound and acoustics practicals — a precise, export-ready choice for institutions sourcing laboratory equipment school India wide and overseas.
Construction and Specifications
A heavy brass pipe is mounted alongside a meter scale, both fitted onto a superior-quality polished wooden board. The lower end of the brass tube is sealed into a metal cup with a side tube connected by rubber tubing to a reservoir, so that raising or lowering the reservoir changes the water level — and hence the length of the air column — inside the pipe. The length of the resonance column is read directly by measuring the distance between the zero stop and the closed end of the tube using the fitted meter rule. This apparatus is used together with EduScope India's Sound tuning fork set, which supplies the tuning forks needed to excite resonance in the air column. For demonstrating resonance and wave phenomena over a defined frequency range, EduScope India also offers a dedicated frequency-demonstration type Resonance Apparatus as a separate product option.
