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. Science Lab Supplies manufactures it in-house at its HSIIDC Industrial Area works in Saha, Ambala, and supplies schools, colleges, distributors and tender contractors directly.
Specifications
A steel crankshaft inside a horizontal frame of structural steel and powder-coated alloy carries offset cams that move an array of 30 indicator rods. Colour-coded tips make one particle easy to follow. The unit measures about 600 x 150 x 300 mm and is driven entirely by hand.

Applications and Experiments for the Wave Motion Apparatus
The apparatus gives a large, repeatable wave that a class can study at its own pace: students follow one rod, compare it with the moving waveform, and measure crest-to-crest distance with a metre rule. 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.
- 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.

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?
Science Lab Supplies, a science apparatus manufacturer in India, makes this apparatus in its own Saha, Ambala factory. Buyers receive quotations directly from the manufacturer, not through a trading intermediary.
