Diameter of newton ring formula

WebOct 11, 2016 · Newton’s ring method is often used to measure many physical parameters. And some measured physical quantity can be extracted by calculating the radius parameter of circular fringes from Newton's ring configuration. The paper presents a new measuring method for radius of circular fringes, which includes three main steps, i.e., determination … WebThe method is based on Newton's equations of motion which are applied to discrete particles. The forces acting on each particle, e.g., the gravitational force or contact forces are balanced. Equation describes the translational velocity u i of a particle resulting from the force balance and Equation its rotational velocity ω i. All forces ...
