Apparatus for Demonstrating the Phenomenon of Wave Propagation and Reflection
Product Code : SCL-PL-11847
Apparatus for Demonstrating the Phenomenon of Wave Propagation and Reflection (SKU SCL-PL-11847) is a water-tank demonstration in which two forks excite waves at two points on the water surface, so a class can watch ripples spread, reflect and overlap. It suits wave topics in secondary and senior secondary physics. The ripple set is manufactured by Science Lab Supplies on Plot 448, HSIIDC Industrial Area, Saha, Ambala, India, which prices and dispatches it itself for schools, colleges, tender contractors and distributors.
Specifications
The table gives every part of the two-source water-wave set on its own line. In short, a water tank is excited at two points by two forks, and a concave lens, a concave-shaped piece, a small diffraction barrier and two Young’s slits can be placed in the water to shape, reflect or split the wavefronts.

Applications and Experiments for the Wave Propagation and Reflection Apparatus
The apparatus makes wave behaviour visible on a water surface: circular wavefronts from each fork, their reflection from a curved piece, bending through a gap and the interference pattern of two sources. It suits Class 9 and Class 11 wave lessons and introductory college physics demonstrations.
- Class 9–11 physics: showing how a disturbance travels outwards as a wavefront.
- Reflection of water waves from the concave-shaped piece, compared afterwards with light focused by a Concave Mirror (50 mm).
- Diffraction of waves through the small barrier gap, a water-surface view of the spreading that Diffraction Gratings with Holder produce with light.
- Interference of two sources, using the two forks or the Young's slits, as a lead-in to Class 12 wave optics on the Adjustable Double Slit Interference Apparatus.
Standard Scope of Supply
A complete set contains the water tank, the two forks that excite the waves, the concave lens, the concave-shaped piece, the small diffraction barrier and the two Young's slits. Water is added at the school, and any extra items requested are itemised on the quotation.
Packing, MOQ and Lead Time
Ask for one demonstration set for a teacher's desk or several for a group of laboratories; the quotation lists packing, delivery time and price for whatever quantity you name. Other school physics lab equipment in India from the same range can be priced on that quotation too.
Science Lab Supplies holds an Importer-Exporter Code as a registered exporter and can ship to buyers in Bangladesh, Zambia, Rwanda, South Africa, Qatar and Sri Lanka. A teacher pricing this ripple set can message the team on the contact page or save it to the enquiry cart; a purchase run as a formal bid can start from the lab tender page.
Frequently Asked Questions
What can students see with this wave apparatus?
They can watch waves spread from the two forks, reflect from the concave-shaped piece, bend through the diffraction barrier and interfere after passing the Young's slits, all on one water surface.
Why does it have two forks?
Two forks excite the water at two points at once, giving two sources whose waves overlap. That makes the interference pattern of two sources visible without extra equipment.
Is Science Lab Supplies the manufacturer or a trader?
Its tank, forks and inserts are manufactured by Science Lab Supplies at its own factory in Saha, Ambala, India. The quotation is prepared at that factory, so no trading intermediary stands between the buyer and the maker.
Can it go on a school laboratory tender?
Yes. Share the tender quantity, the delivery point and any specification sheet, and the set will be quoted item by item against the tank, forks and inserts listed above, with packing and delivery time stated.
