Full experiment with the procedure, table, and formula used have been covered by this video. Please do watch and post your queries and suggestions in the com Newton's rings 151 PROCEDURE: 1. Clean both surfaces of the lens and glass plate with a tissue paper and ensure that there is no ngerprint or grease on either. Place the curved surface of the lens on the glass plate. Check that this is correct by gently pressing on one edge of the lens, it should rock because of the curved surface being in 08/08/2019 by Dr Sushil Kumar. Newtons Ring Experiment Viva an Introduction newtons ring experiment viva include many concepts of interference, you can say it includes all the basic fundamental in this experiment. Objective Determination of the wavelength of a monochromatic source by using Newton's Ring …. Experiment 2: Newton's rings EQUIPMENT NEEDED -Travelling microscope. - Convex lens. -Sodium(monochromatic light) lamp with known wave length . -Glass plate. -Spherometer. -Stand. PURPOSE 1)Explain the formation of Newton's rings . 2)Measure the wave length of the monochromatic light (Sodium). THEORY Newton's ring experiment. 1. Experiment no. 1 Presented by- Group 1 EE Batch 1. 2. In this experiment, we have taken sodium lamp as the monochromatic source. By MONOCHROMATIC SOURCE, we mean a light source which emits particle of particular wavelength and not many wavelengths. Intensity of fringes also depend upon the air column between lens Theory of polynomial Equations: polynomial over an integral domain, division algorithm, division of a polynomial, zero of a polynomial, Rolle's theorem(no proof),properties of equations, Descartes rule of signs, relation between roots and coefficients, application to the solution of an equation, symmetric function of roots, Newton's rings is an interference pattern caused by the reflection of light between two surfaces - a spherical surface and an adjacent flat surface. The constant G, called the gravitational constant, is a proportionality constant necessary to relate the masses, measured in kilograms, to the force, measured in newtons. In the SI system of units, Ghas the value 6.67 × 10−11N m2/kg2. Suppose an object of mass mis on the surface of a planet of mass Mand radius R. 4 Theory of Newton's Ring Circular interference fringes can be produced by enclosing a very thin film of air or any other transparent medium of varying thickness between a plane glass plate and a convex lens of a large radius of curvature. Such fringes were first obtained by Newton and are known as Newton's rings.
