LIT-4B Newton's Ring Experiment Apparatus - Complete Model

Newton's Ring Experiment Apparatus - Complete Model Description The phenomenon of Newton’s rings, named after Isaac Newton, when viewed with monochromatic light, it appears as a series of concentric, alternating light and dark rings centered at the point of contact between the two surfaces. Using this apparatus, students can observe the phenomenon of equal-thickness interference. By measuring interference fringe separation, the radius of curvature of the spherical surface can be calculated.
