An important experimental device that uses interference is the Michelson interferometer. Michelson interferometers are used to make precise measurements of wavelengths and of very small distances. A Michelson interferometer takes monochromatic light from a single source and divides it into two waves that follow different paths. Interference occurs when the two light waves are recombined. The figure below shows the principal components of a Michelson interferometer. A ray of light from a monochromatic source A strikes the beam splitter C,...

5) An ellipsoid refraction problem (you can 't always believe everything you see in a book!) The book Optics by Eugene Hecht, 4th edition, poses the following problem (problem 5.3, somewhat paraphrased). "Referring to the figure below, provide an argument showing that if a point source is placed at the focus Fi of the ellipsoid, the light arrays that emerge from the far side are collimated. L.e., all rays AA' and BB' are parallel to each other and to the...

Part I: Background When a ray of light strikes a smooth surface, it can either reflect, such as with a mirror, or it can both reflect and refract, such as with glass. In this make-up lab activity, we shall look at both situations. This make-up lab shall try to replicate the lab from your lab manual as best possible. Be sure to read the "Discussion" in your regular lab manual. You will be using the Bending Light simulation. Part II:...

Remove the rays from the simulation by clicking on them and then pressing Delete. Place a Point Source at (60,180) by clicking Point Source under Tools, then clicking the simulation at (60,180). Note that the location at which the rays converge is the same as it was using the principal ray method. This is, in fact, why we use the principal ray method: it generates the convergence point using comparatively few lines. As we know from Huygens's principal, every point...

Partner: Date Name 11 Snell's Law Introduction When light passes from one material to another it is always bent away from its original path. This process is known as refraction and the change in direction depends on the change in optical density (or refractive index) of the two materials. A larger change in refractive index results in a larger change in angle between incoming and outgoing light beams. A light beam bends closer to the normal in the material with...

Chapter 10 Lenses Learning Objectives During this lab, you will, use the Law of Sagitta to determine the radius of curvature of a lens use the lens equation to determine focal length, . use the lensmaker's formula to determine the index of refraction of a trans- parent material. 10.1 Pre-lab This pre-lab will introduce you to a concept in geometrical optics known as ray tracing. Given an object that emits or reflects light, you can place a lens in the...

Consider a cylindrical capacitor like that shown in Fig. 24.6. Let d = rb − ra be the spacing between the inner and outer conductors. (a) Let the radii of the two conductors be only slightly different, so that d << ra. Show that the result derived in Example 24.4 (Section 24.1) for the capacitance of a cylindrical capacitor then reduces to Eq. (24.2), the equation for the capacitance of a parallel-plate capacitor, with A being the surface area of...

TORENTO CONSTRUCTION: ETHICAL CONTRACTING On December 27, 2010, Cary Holmes, manager of the Supply Chain Management (SCM) group at Torento Construction Inc. (NCG), was in his office in Torento, Ontario, trying to organize the thoughts running through his head as a result of a recent bidding to save operating costs at NCG. There was no problem in terms of the final outcome; in fact, the bid was going to result in cost savings of 25 per cent, which was exactly...
