Description
Newton's rings are observed by placing a convex lens in contact with a flat glass surface and illuminating the setup with monochromatic light. The resulting interference pattern consists of concentric rings, which are caused by the varying thickness of the air film between the lens and the glass. The spacing of the rings provides information about the curvature of the lens and the wavelength of the light, demonstrating the principles of thin film interference.
