Newton's rings

Newton's rings are a pattern of concentric circular rings seen when a lens is placed on a flat surface, often glass. This phenomenon occurs due to interference of light waves reflecting between the lens and the surface. If the surfaces are slightly curved, light waves either reinforce (add together) or cancel each other out, creating bright and dark rings. These rings can be used to measure the wavelength of light or the curvature of lenses, making them important in optics and physics. The pattern illustrates fundamental principles of light behavior and wave interference.
