Newton Ring Apparatus
Product Code : JA-LOE-7911
The Newton Ring Apparatus (SKU JA-LOE-7911) produces Newton's rings, the circular interference fringes formed in the thin air film between a plane glass plate and a plano-convex surface. It consists of a pair of 60 mm diameter optically polished glass plates, one plane and one plano-convex, mounted together in a metal frame, with three nickel-plated brass screws to adjust the pressure between them. This Newton's rings apparatus for B.Sc practicals is manufactured in India by JaincoLab.
Specifications
The apparatus comprises two 60 mm diameter optically polished glass plates, one plane and one plano-convex, held in a metal frame, with the contact pressure set by three nickel-plated brass screws.

Applications of the Newton's rings apparatus
The apparatus is used in undergraduate optics practicals to observe Newton's rings in reflected monochromatic light and, by measuring ring diameters with a travelling microscope, to find the wavelength of the light or the radius of curvature of the curved surface.
- Determining the wavelength of sodium light from ring diameters
- Finding the radius of curvature of the plano-convex surface
- Demonstrating interference in a thin air film
- Studying how contact pressure changes the central spot and ring pattern
- B.Sc and engineering physics interference practicals
