Product Code : SCL-PL-12129
Wave Motion Apparatus Physics Lab (SKU SCL-PL-12129) is a crank-driven model in which 30 colour-tipped rods move in sequence to show transverse and longitudinal waves. It helps Class 9 and Class 11 students and college physics classes link wave equations to visible motion. Every unit is manufactured in the Science Lab Supplies works at Plot 448, HSIIDC Industrial Area, Saha, Ambala, and priced for schools, colleges, distributors and tender contractors without a middleman.
Specifications
The 30-rod wave model is described row by row in the table. In short, a steel crankshaft with offset cams sits in a horizontal frame of structural steel and powder-coated alloy, moves 30 colour-tipped indicator rods, measures about 600 x 150 x 300 mm and is driven entirely by a detachable hand crank.

Applications and Experiments for the Wave Motion Apparatus
The apparatus gives a large, repeatable wave that a class can study at its own pace: one rod can be followed and compared with the moving waveform, and the crest-to-crest distance measured. It supports Class 9 sound, Class 11 waves, and diploma or B.Sc. lectures on wave motion.
- Class 9 science: transverse versus longitudinal waves.
- Class 11 physics: amplitude, frequency, wavelength and phase difference.
- Measuring the wavelength between consecutive crests along the rod array with a Wooden Ruler 1 Metre or a rule from the Measuring Rulers Set.
- Node and antinode formation within simulated wave boundaries.
Fit the handle into the crankshaft key slot and turn it slowly clockwise; avoid sharp reversals or pressing on the rods, which can misalign the cams.
Standard Scope of Supply
Each unit is supplied with the main assembly frame carrying the rod array, a detachable heavy-duty operating crank handle, a calibration alignment key, and an instruction manual with structured laboratory experiments. A metre rule for wavelength measurements can be added to the quotation.
Packing, MOQ and Lead Time
Science Lab Supplies can quote this school physics lab equipment in India as one apparatus or a set for several physics rooms. The quotation lists packing, delivery time and price for the quantity you name, and can also carry other wave models or a metre rule.
Holding an Importer-Exporter Code, Science Lab Supplies can ship to buyers in Saudi Arabia, Oman, the Philippines, Nepal, Bangladesh and Zambia. State how many physics rooms need the model on the contact page, or save it in the enquiry cart; institutions buying by tender will find the procedure on the lab tender page.
Frequently Asked Questions
How many rods does the apparatus have?
It carries an array of 30 indicator rods with colour-coded tips, moved in sequence by offset cams on a single steel crankshaft turned by hand.
Does it need electrical power?
No. The apparatus is fully mechanical and is driven by the hand crank, so it needs no batteries, adapter or mains connection in the classroom.
How can students find the wavelength?
Stop the crank with the wave in view, pick two consecutive crests, and measure the distance between them along the rod array with a metre rule.
Is Science Lab Supplies the manufacturer or a trader?
The rods, cams and steel frame are built in the company’s own Saha, Ambala factory, which makes Science Lab Supplies the manufacturer; a quotation for this model comes from the factory, not from a trading intermediary.
