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. Teachers use it for wave topics in secondary and senior secondary physics. Science Lab Supplies manufactures the apparatus in Saha, Ambala, India (Plot 448, HSIIDC Industrial Area) and delivers it directly to schools, colleges, tender contractors and distributors.
Specifications
The core of the set is a water tank with two forks that act as a pair of point sources on the surface. A concave lens, a second concave-shaped piece, a small diffraction barrier and a pair of Young's slits can be placed in the water to shape, reflect or split the advancing 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.
- Diffraction of waves through the small barrier gap.
- Interference of two sources, using the two forks or the Young's slits, as a lead-in to Class 12 wave optics.
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. Enquiries are welcome on the contact page or via the enquiry cart, and larger institutional orders 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?
The manufacturer. Production takes place at the company's factory in Saha, Ambala, India, and prices are quoted from there with no trading intermediary.
Can it go on a school laboratory tender?
Yes. Share the tender quantity and delivery point and it will be quoted item by item against the contents listed above.
