Wave Machine
Product Code : LSK-PL-10355
Wave Machine (SKU LSK-PL-10355) is a 480 mm wave demonstrator in which a set of rotating cams raises and lowers 24 vertical rods, so a class can watch both transverse and longitudinal waves form and travel. It suits the introduction of wave motion in secondary school and its revision in Class 11. Science Lab Supplies manufactures the cam mechanism and rods at Plot 448, HSIIDC Industrial Area, Saha, Ambala, India, and the factory sends quotations straight to schools, colleges, tender contractors and distributors.
Specifications
Rod count, length and handle scale of the 24-rod cam demonstrator are given row by row. In short, turning the handle rotates a row of cams that lift and lower the rods with highlighted plastic tips; eight rods are turned at 90 degrees to simulate transverse motion, and the machine runs almost silently without lubrication.

Applications and Experiments for the Wave Machine
The machine shows that particles of a medium only oscillate about fixed positions while the wave form moves along. Because students can view it from both sides, it suits whole-class demonstrations in the sound chapter of Class 9 science and the waves chapter of NCERT Class 11 physics.
- Class 9 science (CBSE/NCERT): sound as a longitudinal wave of compressions and rarefactions, followed by real vibrations from the 256 Hz forks of the Tuning Fork Set.
- Class 11 physics: comparing transverse and longitudinal waves, wavelength and amplitude, then standing waves on a string with the Melde's String Vibration Apparatus.
- Phase lessons: using the degree scale on the handle to relate rotation angle to the position of each rod.
Standard Scope of Supply
The Wave Machine is supplied as a single unit as described above: the cam assembly with its 24 tipped rods and the handle with its degree scale, 480 mm long. Any further wave apparatus for the same lessons can be added as separate lines on the quotation.
Packing, MOQ and Lead Time
You can ask us to quote one wave machine for a demonstration bench or several for a department. The quotation states the packing, delivery time and price for your quantity, and other wave apparatus can be added to it for a single delivery.
With an Importer-Exporter Code on record as a registered exporter, Science Lab Supplies can ship to buyers in Qatar, Sri Lanka, Vietnam, Malaysia, Peru and Egypt. A wave-lesson order can start with a few lines on the contact page or a basket in the enquiry cart, and any tender-based purchase is covered on the lab tender page.
Frequently Asked Questions
Can one wave machine show both kinds of wave?
Yes. The 24 rods rise and fall in sequence to show a travelling wave, and eight of them are turned at 90 degrees to simulate transverse motion, so both wave types can be discussed with one apparatus.
Does the machine need oiling or maintenance?
No lubrication is required. The mechanism is strong and almost silent in operation, which helps when the teacher is explaining to the class while turning the handle.
How is the degree scale used?
The circular scale on the handle shows how far the cams have rotated, so students can link the angle of rotation to how far the wave has advanced along the rods.
Is the Wave Machine made by Science Lab Supplies?
Yes. Cams, rods and the scaled handle are assembled into the finished machine at the company’s Saha, Ambala, India plant, and buyers receive their quotation from that manufacturing plant rather than a reseller.
