Kinetic Theory Model
The Kinetic Theory Model apparatus is used along with the vibration generator to demonstrate the movement of molecules in a gas. An approximate relationship between the floating height, i.e., volume of the gas and weight of the disc, i.e., pressure of the gas can be observed. The platform has a rubber surface and small stainless steel balls are loaded into the tube. With the change in the speed of vibration generator, the heating of the gas stimulates resulting change in the agitation of the balls inside the tube. It comprises theory of piston, steel balls and a base or placing on an overhead projector.

Chladni Plates Square and Round Plate
The Chladni Plates Kit allows the continuous vibrations to be produced at measurable frequencies to determine the resonant frequencies of the plates and examine the modes of vibration at any frequency. A thin layer of sand is spread over the plate. The sand collected along the nodal lines of the wave patterns painted clear and beautiful pictures of the various modes of vibration. The plate’s resonances are audible. Kit is made of metal sheet in two shapes: square and round. The round plate can be vibrated about its center or an offset point to investigate both symmetric and asymmetric modes of vibration.

Vibration Pattern Demonstration Kit
The Vibration Pattern Demonstration Kit is designed to visually demonstrate the behavior of vibrating surfaces and the formation of standing wave patterns. When fine sand or salt is sprinkled on the metal plate and the plate is excited at different frequencies, the sand gathers along the nodal lines where there is no vibration, creating beautiful geometric patterns known as Chladni figures. This provides a clear and engaging way to study the relationship between vibration, frequency, and wave motion. This apparatus helps students develop a deeper understanding of wave phenomena through direct observation and hands-on experimentation.
