Steel Strips for Resonance
The resonance strips are designed to demonstrate the relationship between the frequency and wavelength of a cantilevered beam. The steel strips when used with the Vibration Generator show resonance at different frequencies The resonant frequencies of resonance strips depend on the different lengths of the strips. The apparatus provides three steel strips with holes at different length and connected with one another through a screw.

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.

Magna Probe
A tool for visualizing the three-dimensional nature of magnetic fields. The sensitive probe allows students to observe magnetic effects in space with clarity. Ideal for individual or group experiments, it provides an engaging way to understand complex concepts in physics through hands-on learning.
Features:
- Small Alnico bar magnet with clear N–S marking
- Non-magnetic gimbal mount for free movement in X, Y, Z axes
- Highly sensitive probe for precise demonstrations
- Approximate Dimensions: 120 mm (head width) × 280 mm (length)
