Newton's rings - Wikipedia
WEBNewton's rings is a phenomenon in which an interference pattern is created by the reflection of light between two surfaces, typically a spherical surface and an adjacent touching flat surface. It is named after Isaac Newton, who investigated the effect in 1666.

WEBFeb 3, 2023 · Newton’s rings are a series of concentric circular rings consisting of bright- and dark-colored fringes. When a plano-convex lens lies on top of a plane lens or glass sheet, a small layer of air is formed between the two lenses.

WEBNewton’s rings, in optics, a series of concentric light- and dark-coloured bands observed between two pieces of glass when one is convex and rests on its convex side on another piece having a flat surface. Thus, a layer of air exists between them.

WEBNewton's Rings. Isaac Newton first discussed the colored interference fringes that we now call Newton's Rings in a communication to the Royal Society in December 1675, and presented an expanded account in his book "Optics" (1705).

WEBNewton's Rings. What it shows: Waves reflecting from two surfaces can interfere constructively and destructively. In this case it is light waves that are being reflected at glass/air and air/glass interfaces. The interference produces a concentric ring pattern of rainbow colors in white light, or dark and light rings in monochromatic light.
Interference - Newton's rings: Physclips - Light - UNSW Sites
WEBNewton's rings are interference patterns formed by light incident on the thin film of air between a convex lens and a flat (or between two suitable lenses). Here we explain the phenomenon and analyse its geometry.
Newton's Rings
WEBNewton's rings is the name given to the bulls-eye type interference pattern obtained when a spherical piece of glass (a watch glass, for instance) sits on a flat piece of glass. This creates a thin film between the two pieces of glass with a thickness depending on the distance from contact point.

WEBNewton's rings. In Newton's rings, a curved watch glass sits on top of a flat piece of glass. A thin film of air is in between the two - the thin film has a thickness that is zero where the two pieces of glass touch, and gradually increases as you move away from that point.
