As shown in the figure below, two transparent polycarbonate plates, each 19.0 cm long, touch each other at the right end, but are separated by a thin cylinder with a diameter of d = 0.0580 mm at the left end. (The plates are surrounded by air.) Light consisting of two wavelengths, 400 nm and 600 nm, is incident on and normal to the surface of the plate, and is viewed by reflection. At what distance from the contact point is the next dark fringe? X mm
A plano-convex lens with radius of curvature R = 3.2 m is in contact with a flat plate of glass. A light source and the observer's eye are both close to the normal, as shown in the figure below. The radius of the 51st bright Newton's ring is found to be 9.4 mm. What is the wavelength of the light produced by the source? nm 2//1 Need Help? Read It 8:36 PM 4/11/2021
Fig. 1 shows a laser beam incident on a piece of wet filter paper placed on a glass plate whose 'refractive indexglass plate whose refractive index is to be measured (the rays are represented in the figure). Explain what happens anddeduce an expression for ni in terms of R and d. Consider the refractive index of air to be 1.Note: Remember that all light that falls on a reflecting surface always has part of the light reflected, being refracted or not.refracted or not. Moreover, θc in the figure represents the critical angle at which we have the condition of total internal reflection
