Apparatus for Studying Interference from Jungian Cracks and Diffraction by Means of Diffraction Nets
Product Code : SCL-PL-11845
Apparatus for Studying Interference from Jungian Cracks and Diffraction by Means of Diffraction Nets (SKU SCL-PL-11845) is a laser-based wave optics set for Young's double-slit interference and diffraction experiments, with an optical bench, screen, slits, lenses and liquid-filled optics. It serves Class 12 wave optics and B.Sc. physics practicals. Science Lab Supplies manufactures the set at Plot 448, HSIIDC Industrial Area, Saha, Ambala, India, and quotations for schools, colleges, tender contractors and distributors are drawn up there directly.
Specifications
Each lens, plate, sheet and hollow optic of the Young's slit set is given its own row. In short, a laser diode on an optical bench lights a diffraction slit or one of 13 objects, the pattern is read on a screen against a 100 cm ruler, and lenses, a polarizing sheet and oil-filled optics extend the work.

Applications and Experiments for the Young's Slit and Diffraction Apparatus
Students can shine the laser through the diffraction slit or one of the 13 objects, measure fringe spacing on the screen and calculate wavelength or slit separation. The same bench serves single-slit diffraction, polarization with the polarizing sheet, and refraction through the oil-filled lenses and prism.
- Class 12 physics: Young's double-slit experiment and single-slit diffraction.
- B.Sc. practical: wavelength of laser light from fringe width or a diffraction grating.
- Polarization and refraction: crossing the polarizing sheet with a Polaroid Disc Mounted, and comparing the oil-filled prism with the four prisms of the Laser Refraction Chamber Set.
In the product title, "Jungian cracks" means Young's slits and "diffraction nets" means diffraction gratings. Never look into the laser beam or its reflections; paraffin oil is flammable, so keep it away from flames.
Standard Scope of Supply
The apparatus includes the laser diode, optical bench, screen, set of 13 objects, diffraction slit, four lenses (−10, −5, +10 and +20 cm), a 100 cm plastic ruler, two reflective surfaces, a glass plate, a polarizing sheet and the three hollow optics. Ask us whether paraffin oil can be added to the quotation.
Packing, MOQ and Lead Time
Quotations are prepared for one apparatus or several for a wave-optics laboratory, each with the packing, delivery time and price for that quantity. Diffraction gratings, polarizing filters and other physics lab equipment in India can be added to the same quotation.
Science Lab Supplies holds an Importer-Exporter Code and has the capability to ship to buyers in the Philippines, Nepal, Bangladesh, Zambia, Rwanda and South Africa. A wave-optics bench can be priced once you write through the contact page or forward your enquiry cart; university and school tenders are handled via the lab tender page.
Frequently Asked Questions
What is this interference and diffraction apparatus used for?
For Young's double-slit interference, single-slit and grating diffraction with a laser diode, plus polarization and refraction work using the 200 x 200 mm polarizing sheet and the three oil-filled optics.
Is Science Lab Supplies the manufacturer or a trader?
This laser wave-optics set is produced at the Science Lab Supplies factory in Saha, Ambala, India; the company is its manufacturer, and the factory itself answers enquiries and issues each quotation.
Is the laser safe for students?
Only under supervision. Students should never look into the beam or at reflections from the reflective surfaces, and the laser should be switched off when not in use.
