Description
Newton Rings are produced using an arrangement in which a plano convex lens with an extremely slight curvature is touching a glass plate, so that an air wedge with spherical curved boundary surface is formed. When this configuration is illuminated with a vertically incident, parallel light beam, concentric interference rings (Newton’s Rings) are formed around the point of contact between two glasses surface both in reflection and in transmitted light. These Newton’s rings are used for measuring wavelength of monochromatic light source. This system also works with white light source like mercury lamp.
Experiment Performed
- To determine the wavelength of monochromatic light source ( Red, Blue, Green, Yellow )
Feature
- All components are made out of anodized aluminum and stainless steel to avoid corrosion
- Holders with adjustable height and compatible in optical rail
- Optics used for design have very good surface quality
- Newton Plate have large radius of curvature
