Storage Box 740-09892 Introduction The PASCO Basic Optics System contains the optics components you will need for a variety of experiments and demonstrations. This manual includes student instructions and teacher’s notes for 17 typical experiments. For an even greater variety, you can expand the system with any of the Basic Optics kits and components available from PASCO, including lasers, polarizers, diffraction slits, and light sensors. See the PASCO Physics catalog or visit www.pasco.com for details. ® 5 Basic Optics System About the Equipment About the Equipment For detailed information on the Light Source, Ray Table, Adjustable Lens Holder, and Ray Optics Kit, see the instruction sheets included with those components. Optics Bench Basic Optics components, such as mounted lenses and the adjustable lens holder, snap into the wide central channel of the optics bench. Place the base of the component on the bench and push down firmly to snap it in place. To move it, squeeze the tab on base and slide it along the bench. Components that include a square bolt and a thumb screw are designed to be fasted to the T-slots on the sides and center of the bench. Slide the bolt into the T-slot, insert the thumb screw through the component’s mounting hold, thread the screw into the bolt and tighten it down. metric scale for measuring component positions Use the metric scale on the bench to measure the positions of components. Light Source The included light source can be used on a tabletop or mounted on the bench. It functions as a bright point source, an illuminated crossed-arrow object, a primary-color source, and a ray box with up to five parallel rays. T-slots Mounted Lenses The Basic Optics System includes four lenses mounted in holders. Use them on the optics bench with the light source, viewing screen, and other Basic Optics components. Adjustable Lens Holder To use an unmounted lens on the bench, place it in the adjustable lens holder. It will hold any round lens between 20 and 75 mm in diameter. Viewing Screen lenses. Mount the screen on the bench to view real images formed by Concave/convex Mirror and Half-screen The mounted mirror is concave on one side and convex on the other side. The radius of curvature of both surfaces is 200 mm. Use the half-screen to view real images formed by the concave side of the mirror. Ray Table and D-shaped Lens Use the ray table and D-shaped lens on a tabletop with the light source (in ray-box mode) to study angles of incidence, reflection and refraction. Ray Optics Kit The ray optics kit is a set of optics components designed for use with the light source in ray-box mode. To make the rays easy to see and trace, use the ray optics components on a white sheet of paper on a flat table top. The transparent storage box doubles as a water tank for studying lenses under water. 6 ® Model No. OS-8515C Storage Box Storage Box Use the foam-padded box to store, organize, and protect the system’s components. Place the components in the fitted compartments as illustrated below. Extra compartments are included for additional components as spare parts. A full-page diagram appears on page 69. Remove or copy that page and attach it the box lid. Concave/convex Mirror Ray Optics Kit AC Adapter Light Source D-shaped Lens Viewing Screen Half-screen -150 mm +250 mm +200 mm +100 mm Ray Table and Adjustable Lens Holder Lenses About the Experiments The experiment instructions on the following pages are arranged and categorized according to which components of the Basic Optics System they use. See the table at the top of each experiment for a detailed list of required equipment. Teachers’ notes, including typical data and answers to questions, can be found starting on page 59. The experiments that call for the light source work best in a dimly lit room. Ray Optics Kit Experiments These experiments use the Ray Optics Kit, the Light Source (in ray-box mode), and may require blank white paper, a ruler, protractor, and drawing compass. 1. Color Addition (page 9): Explore the results of mixing colored light and illuminating colored ink with colored light. 2. Prism (page 11): Show how a prism separates white light into its component colors and show that different colors are refracted at different angles through a prism. 3. Reflection (page 13): Show how rays are reflected from plane, concave, and convex mirrors. 4. Snell’s Law (page 15): Determine the index of refraction of acrylic by measuring angles of incidence and refraction of a ray passing through the trapezoid. 5. Total Internal Reflection (page 17): Determine the critical angle at which total internal reflection occurs in the trapezoid. ® 7 Basic Optics System About the Experiments 6. Convex and Concave Lenses (page 19): Use ray tracing to determine the focal lengths of lenses. 7. Hollow Lens (page 21): Use the hollow lens and water to explore how the properties of a lens are related to its shape, its index of refraction, and the index of refraction of the surrounding medium. 8. Lensmaker’s Equation (page 23): Determine the focal length of a concave lens by measuring its radius of curvature. 9. Apparent Depth (page 25): Measure the apparent depth of the trapezoid and determine its index of refraction by comparing the apparent depth to the actual thickness. Ray Table Experiments These experiments use the Ray Table with the D-shaped Lens and the Light Source (in ray-box mode). 10. Reversibility (page 29): Explore how the relationship between the angles of incidence and refraction is related to the direction of propagation. 11. Dispersion (page 31): Show how white light is separated into colors by the acrylic D-shaped lens and determine the different indices of refraction for red and blue light. Optics Bench Experiments These experiments use the Optics Bench, Mounted Lenses, and Viewing Screen. Experiments 12 and 17 also use the Light Source. 12. Focal Length and Magnification of a Thin Lens (page 33): Determine the focal length of a converging lens and measure the magnification for a certain combination of object and image distances. 13. Focal Length and Magnification of a Concave Mirror (page 37): Determine the focal length of a concave mirror and measure the magnification for a certain combination of object and image distances. 14. Virtual Images (page 41): Study virtual images formed by a diverging lens and a convex mirror. 15. Telescope (page 47): Construct a telescope and determine its magnification. 16. Microscope (page 51): Construct a microscope and determine its magnification. 17. Shadows (page 55): Show the umbra and the penumbra of a shadow. 8 ® Model No. OS-8515C E x p e r i m e n t 1 : C o l o r A d d it i o n Experiment 1: Color Addition Required Equipment from Basic Optics System Light Source Convex Lens from Ray Optics Kit Other Required Equipment Red, blue, and black pens Blank white paper Purpose Light source In Part 1 of this experiment, you will discover the results of mixing red, green, and blue light in different combinations. In Part 2, you will compare the appearance of red, blue, and black ink illuminated by red and blue light. Convex lens Folded paper Part 1: Addition of Colored Light Procedure 1. 2. Red, green, and blue rays Turn the wheel on the light source to select the red, green, and blue color bars. Fold a blank, white sheet of paper, as shown in Figure 1.1. Lay the paper on a flat surface and put the light source on it so that the colored rays are projected along the horizontal part of the paper and onto the vertical part. Combined colors Figure 1.1: Color addition Place the convex lens near the ray box so it focuses the rays and causes them to cross at the vertical part of the paper. Note: The lens has one flat edge. Place the flat edge on the paper so the lens stands stably without rocking. 3. What is the resulting color where the three colors come together? Record your
