Mechanical-Wave Apparatus Package
Product Code : SCL-PL-12388
Mechanical-Wave Apparatus Package (SKU SCL-PL-12388) combines a sine-wave generator, a mechanical wave driver, two Chladni plates, a resonance loop, a spring and cords to demonstrate transverse, longitudinal and standing waves and resonance in school and college physics. Science Lab Supplies manufactures the package in its factory at Plot 448, HSIIDC Industrial Area, Saha, Ambala, India, and schools, colleges, tender contractors and distributors can order it directly.
Specifications
The generator runs on 220 V and gives a sine output from 1 to 400 Hz in 1 Hz steps and from 10 to 4000 Hz in 10 Hz steps. It drives the mechanical wave driver, which vibrates the plates, loop, spring or cord.

Applications and Experiments for the Mechanical-Wave Apparatus
The package produces standing waves on a cord, compressions on a spring and nodal patterns on Chladni plates, so students can relate frequency, wavelength and wave speed. It covers the waves chapter of Class 11 physics and B.Sc. wave practicals, and is versatile school physics lab equipment in India.
- Class 11 physics (waves): standing waves on the elastic cord at set frequencies.
- Longitudinal compressions and rarefactions on the spring.
- Chladni patterns and resonance modes of the wire loop and metal plate.
The generator is mains-powered at 220 V; start at low amplitude and keep it away from water.
Standard Scope of Supply
The package contains the 220 V sine-wave generator, the wave driver with leads, hex key and clamp, square and circular 24 cm Chladni plates, sand and shaker, resonance loop, resonance plate, spring, transverse-wave cord, 7 ft elastic cord, mounting fixture, hook and clamps.
Packing, MOQ and Lead Time
A quotation can be prepared for one package for the teacher's bench or several for group practicals. Science Lab Supplies, a physics instruments supplier in India, lists packing, delivery time and price for that quantity, and other wave or sound apparatus can be included on it.

Frequently Asked Questions
What frequency range does the signal generator cover?
The sine-wave generator covers 1–400 Hz with 1 Hz resolution and 10–4000 Hz with 10 Hz resolution. It runs on 220 V and drives the mechanical wave driver in the package.
How are the Chladni plates used?
Fine sand is sprinkled on the square or circular plate while the driver vibrates it. The sand gathers along the nodal lines, showing the standing-wave pattern at each resonant frequency.
Is Science Lab Supplies the manufacturer or a trader?
Science Lab Supplies manufactures the package rather than trading it. It is put together in the company’s factory at Saha, Ambala, India, and every quotation is issued directly by that factory.
Related Wave and Sound Apparatus
These four Physics Lab items pair naturally with the wave package: a separate audio-frequency generator, a stand-alone vibration generator, Melde’s string apparatus for standing waves and a cam-driven wave machine for slow visual demonstrations, and all four can share one quotation.
- Audio-Frequency Generator — 1–100 kHz generator with 0–10 V output.
- Vibration Generator — coil-and-magnet driver used with a function generator.
