Witrynaaround the point of contact. These rings were first discovered by Sir Isaac Newton, hence named as Newton's Rings. If it is viewed with the white light then coloured fringes are obtained. The experimental arrangement of the Newton’s Ring apparatus is shown in figure 1. Fig. 1: Experimental arrangement of the Newton’s Ring apparatus Witrynatoday we know white light is made of the seven colours of the rainbow but how did we figure this thing out well you may already know the answer to this prisms prisms are …

WitrynaNumber of rings produced in air. (a) In Newton’s ring experiment, as air film of variable thickness is obtained between glass plate and convex surface .in this case, the radii of fringes for interference maxima is calculated as follows, r = m + 1 2 λ R r 2 λ R = m + 1 2 m = r 2 λ R - 1 2. Here, m represents number of fringes, r is radius ... WitrynaExplanation: In Newton's ring experiment the rings formed due to interference of reflected rays from the upper and lower surfaces of the air film developed between the convex surface of the plano-convex lens and the plane glass plate. The interference of light results in lower, higher, or same amplitude of the light. WitrynaNewton's rings. 1. Interference by multiple beam reflections: Newton’s Rings Aim: 1. Studying the interference phenomenon due to multiple reflections of light waves from gradually varying air film. 2. Determination of the wavelength of a monochromatic light using Newton’s rings. Apparatus: Plano – convex or bi - convex lens, monochromatic ... brother printer scanning with lines
