Reflection, Refraction, Dispersion APPARATUS 1. A lamp housing containing a tungsten filament lamp and a lens which when properly adjusted with respect to the source will produce a beam of parallel light. 2. A drawing board on which a plate with five parallel, vertical slits is mounted. On the board side of this plate are two movable shutters which can control the number of exposed slits. On the source side of the plate there are channels to hold filters. 3. A box containing a red filter, a blue filter and the following optical parts: (letters have been assigned to these parts and these will be referred to by the appropriate letter in the following directions). C A M E T A L B D E F G 9 0 ° 4 5 ° 4 5 ° 6 0 ° H The bottom surface of each glass piece (C through H) is frosted; thus the path of a beam will be visible as it passes through the piece. Caution: Handle optical parts with care, keep surfaces clean. Use only the lens paper supplied to clean them. Keep all parts in their proper compartments in the box when they are not in immediate use. 1

INTRODUCTION The following exercises illustrate the basic behavior of light rays undergoing reflection and refraction in simple mirrors, lenses etc. All of these effects follow from Snell’s law and the law of reflection which may be taken as empirical rules. Before coming to the laboratory read the chapters in your text which relate to reflection, refraction, mirrors and lenses. PROCEDURE Place the lamp housing with its lens about an inch from the slits. Place a piece of white paper on the board, [Lens paper may be obtained from the instructor’s desk.) Expose all five slits to the source. Adjust the position of the source relative to the board so that all five beams are visible on the paper, are parallel to each other, are perpendicular to the slit plate, and are approximately of equal intensity.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
