Newton Ring Apparatus Newton Ring Apparatus – Physics Apparatus Interference fringes are clearly seen when newton ring apparatus is viewed in sunlight, fluorescent light or monochromatic light. The glass plate and convex lens are held in a heavy aluminum frame having three adjusting screws. The frame is 9 cm in diameter and aperture is 5 cm. The Newton Ring are used to study constructive and destructive interference. Pressure between the two glass plates adjustable by three spring-loaded screws.
