In 1717, Sir Isaac Newton studied the rings pattern generated due to interference of light. ... Newton's ring pattern is a result of interference between the partially reflected and partially transmitted rays from the lower curved surface of plano-convex lens and upper surface of the plane glass plate.

What is the result of Newton's ring experiment?

At positions where the path length difference is equal to an even multiple (2n)of a half-wavelength (b), (Lambda by 2)the reflected waves cancel, resulting in a dark spot. This results in a pattern of concentric bright and dark rings, interference fringes.

What is the conclusion of Newton's ring experiment?

Conclusions. The proposed method can obtain the radius data of each order closed circular fringes. Also, it has several other advantages, including ability of good anti-noise, sub-pixel accuracy and high reliability, and easy to in-situ use.
