1. Laser light having a wavelength of 632.8 nm is shone on a double slit having a slit spacing of 0.100 mm. The double-slit interference pattern is projected onto a screen 1.844 m from the slits. At a point on the screen 3.50 cm from the zero order maximum, is the screen bright or dark? 2. According to Babinet's principle, coherent light incident on a thin wire will produce a diffraction pattern which is the same as that of a narrow slit with the same dimensions as the wire. You want to use this principle to measure the width of a thin wire. The wire is placed in a beam of laser light having a wavelength of 632.8 nm, and the resulting diffraction pattern is projected onto a screen 2.00 m from the wire. The width of the central maximum of the diffraction pattern, i.e. the distance between the first order minima on either side of the central maximum, is measured to be 3.19 cm. What is diameter of the wire? 3. An object is placed 4.50 cm in from of a concave spherical mirror. The image produced has a magnification of -2.00. What is the radius of curvature of the mirror? 4. You stand in front of a convex spherical mirror having a radius of curvature equal to -1.50 m. The magnification of your image is +0.250. How far from the mirror are you standing?
