Triangular Prism
Product Code : SCL-CL-11879
Triangular Prism (SKU SCL-CL-11879) is a three-sided optical prism, 5 cm high and 3 cm wide, with flat polished rectangular faces for bending and dispersing light. Passing white light through it splits the beam into the seven visible colours, while a narrow ray shows refraction and deviation. It suits light chapters from Class 7 to Class 12. Enquiries from schools, colleges, training institutes, distributors and tender contractors are answered by Science Lab Supplies in Ambala, India.
Specifications
Shape, faces and size of the 5 × 3 cm prism appear row by row in the table. In short, the prism has a triangular cross-section with three flat, polished rectangular faces; light entering one face is refracted, deviated and dispersed as it passes through and leaves by another, giving a clear demonstration of basic optics.

Applications and Experiments for the Triangular Prism
With the prism, students can trace how a ray bends at each face, measure the angle of deviation, and see white light split into a spectrum. These are core practicals in the light chapters of NCERT Class 10 science and ray optics in Class 12 physics, and the prism also serves general science demonstrations.
- Class 7–8 science: splitting white light into colours.
- Class 10 science: tracing the path of a ray through a triangular prism with pins and marking the angle of deviation.
- Class 12 physics: angle of deviation against angle of incidence, and minimum deviation; a Ray Box and Lens Set with its prism table can be added for beam work.
- Dispersion demonstrations, comparing this prism with the equilateral and right-angle sizes of Prism Glass.
Handle the prism by its triangular ends so fingerprints do not mark the polished faces.
Standard Scope of Supply
The Triangular Prism is supplied as a single unit, 5 cm high and 3 cm wide with polished faces. A light source, pins and drawing board are separate items; any of them, or other optional accessories you request, can be itemised on the quotation with the prism.
Packing, MOQ and Lead Time
A single prism or one per student pair for ray-tracing practicals can be quoted. Each quotation gives packing, delivery time and price, and as a laboratory glassware supplier in India, Science Lab Supplies can add slabs and other optics items to the same document.
Under an Importer-Exporter Code, Science Lab Supplies can ship to buyers in Iraq, Nigeria, Kenya, Ghana, Ethiopia and Tanzania. Send the number of prisms you need through the contact page or tick them into the enquiry cart for a price; guidance for tender buyers sits on the lab tender page.
Frequently Asked Questions
What size is the prism?
The prism is 5 cm high and 3 cm wide, with a triangular cross-section and three flat, polished rectangular faces for refraction, deviation and dispersion work.
Why does white light split into colours in a prism?
Each colour is refracted by a slightly different amount, so the colours leave the prism at different angles and spread into a spectrum of seven visible colours.
Who supplies the Triangular Prism?
The prism is quoted and dispatched by Science Lab Supplies from Ambala, India, for schools, colleges, training institutes, distributors and tender contractors in any quantity they need.
Is it suitable for the Class 10 prism ray-tracing practical?
Yes. Its flat polished faces let students trace an incident ray, the refracted ray and the emergent ray with pins, then measure the angle of deviation.
