Product Code : EL-PC-2897
Jlab Export is a leading Refraction Through a Glass Slab Manufacturer,and suppliers in India
Refraction Through a Glass Slab (code EL-PC-2897) is a 58 x 90 cm physics wall chart on how a ray of light bends as it enters and leaves a rectangular glass slab, for optics lessons and the ray-tracing practical in secondary-school science. It is printed in full colour on 130 gsm coated art paper, laminated on both sides and hung on plastic rollers. JLab (Jain Laboratory Instruments Pvt Ltd, Ambala, India) supplies it to schools, colleges and dealers.

What Is the Glass Slab Refraction Chart Used For?
When light passes at an angle from air into glass it slows down and bends towards the normal; on leaving the opposite face it bends away from the normal again. Because the two faces of a rectangular slab are parallel, the emergent ray comes out parallel to the incident ray but shifted sideways. This shift is called lateral displacement, and it grows with the thickness of the slab and the angle of incidence. The chart keeps the topic on the classroom wall at a size the whole class can read.
Tracing the path of a ray through a rectangular glass slab for different angles of incidence is one of the CBSE class 10 science practicals: students fix pins on a drawing board, draw the normals and measure the angles of incidence, refraction and emergence. The listing does not describe the individual diagrams printed on this chart, so ask JLab for a preview image if you want to compare it with your lab manual. Because the laminated surface is markable and washable, a teacher can draw extra normals or angles on it during the lesson and wipe them off afterwards.
What to Specify When Ordering
- Quantity — the minimum order is 10 units, supplied as individual charts.
- Glass slabs for the practical — the slab is a separate catalogue item and can be quoted on the same enquiry.
- Other optics titles — refraction through prisms, lenses and reflection of light are listed in the same 58 x 90 cm format.
- Delivery details — destination country, port or city, and the delivery terms (for example FOB or CIF) for an export quotation.
Frequently Asked Questions
Does this chart suit the class 10 glass slab practical?
Its topic is refraction through a rectangular glass slab, which is what that practical studies. The listing does not detail the diagrams, so request a preview image to check it against the way your lab manual draws the experiment.
What size is the chart and how is it hung?
It measures 58 x 90 cm overall and is fitted with plastic rollers for wall hanging. Rolled up, it is about 58 x 4 x 2 cm and weighs 228 g.
Is a glass slab included?
No. This listing covers the wall chart only; a glass slab for the practical is a separate item that can be added to the same enquiry.
Can teachers write on the chart?
Yes. Both sides are laminated with 30 micron heat-sealable polyester film, and the surface is specified as markable and washable.
Which language is it printed in?
English only. It is printed in full colour by offset printing with CTP technology on 130 gsm coated art paper.
Who supplies the Refraction Through a Glass Slab chart?
JLab — Jain Laboratory Instruments Pvt Ltd of Ambala, Haryana, India — supplies it and quotes for it directly, together with its other physics charts and optics apparatus.
Supplier
JLab is the trading name of Jain Laboratory Instruments Pvt Ltd, a company incorporated in 2017 and based on Hargolal Road, Ambala, Haryana. Alongside the laboratory apparatus it makes itself, JLab supplies printed science charts such as this one, so a school can order its optics charts and its glass slabs and prisms from a single source. Each chart is checked visually before it is packed, and JLab exports worldwide, with buyers in every region — for example Iceland in Northern Europe, Guyana in South America, Gambia in West Africa, Bangladesh in South Asia and Italy in Southern Europe. Tender buyers can find details on the JLab lab tenders page.
Optics Apparatus and Companion Charts
- Glass Slab — a rectangular slab of bubble-free glass with all sides polished, for the ray-tracing practical.
- Prism Acrylic Set of 6 — clear acrylic shapes with polished sides for studying how light behaves in different shapes, kept in a wooden box.
- Refraction Through Prisms — the companion chart on light passing through a triangular prism.
- Refraction of Light Through Lenses — the series chart on convex and concave lenses.
- Reflection of Light — the series chart on plane and curved mirrors.
The rest of the series is listed under Physics Charts, and every subject range is in Charts.
