R-1 RESULTS Group Lab Report * Title of Experiment: Geometric Optics Date: 3/19/2024 Class, Section & Lab group: PHYS246-230 Group 4 Recorder Amman Khorsandi Group Members PRESENT Leo Worku, Noreen Ramzy, Amman Khorsandi * Before beginning, save this report on your desktop with the Recorder's last name appended. Activity I 4. What is the resulting color where the three colors come together? Record the results. Yellow 5. Now block the green light ray with a pencil. What color results from adding red and blue light? Record the results. Reddish-pink 6. Block each color in succession to see the addition of the other two colors and complete table 1. Blocking red: Teal ; Blocking blue: yellow. 7. Mixing colored light and mixing colored paint are two different processes. Do those two processes have the same result? Why or why not? Explain. They will be different due to the varying frequencies of the colors. The pigmentation of the paint will also affect the result of color mixture. Ex: Blocking blue gives yellow, white mixing red and green paint yields a brownish color. 8. White light is said to be the mixture of all colors. In this experiment, did mixing red, green, and blue light result in white? Explain. It did, as using a convex lens combined all to yield white light. Activity II 3. Now the group member which had his/her eyes covered, looks at the paper that has been placed in front of the colored light. What colors do the two lines appear to be? Record your observations in Table 2. With red light: Red ink as red, and black ink as black. With blue light: Red ink as purple and black ink as a very dark blue.

R-2 Activity III 7. Rotate the trapezoid until the angle (θ) of the emerging ray is as large as possible and the ray separates into colors. What colors do you see? In what order are they? Draw the contours of the prism on the paper and mark the exit of the red, green, and blue light. Red , yellow , green , and blue in that order. 8. Without repositioning the light source or the trapezoid, turn the wheel on the light source to select the three primary color rays. The colored rays should enter the trapezoid at the same angle that the white ray did. Do the colored rays emerge from the trapezoid parallel to each other? The colored rays emerge from the trapezoid parallel to each other. 9. Do the individual colored light rays exit at the same angle as the white light constituent of the same color did? They do emerge at the same angle . Activity IV 14. Are your results in agreement with the law of reflection? Yes, because the angles of incidence are almost exactly (or exactly) as expected. Activity V 16. Is the ray bent when it passes out of the lens perpendicular to the curved surface of the lens? If it is, you should make sure the light ray enters the center of the cylindrical lens. When it is exactly perpendicular, there is no bending. 17. Now repeat the procedure for three different angles of incidence. Measure and record the angle of incidence and the angle of the refracted ray in the table 4. 10 degrees angle of incidence: 9 degrees angle of refraction 20 degrees angle of incidence: 17 degrees angle of refraction 30 degrees angle of incidence: 26 degrees angle of refraction 18. Was all the light of the ray refracted? Was some reflected? There is mostly refraction, and a barely noticeable amount of reflection.

R-3 19. How could you improve the accuracy of the results? Angle the lens against the light more accurately and straighten out the lens along the component line more properly. 20. The accepted value is 1.49, and the measured value is 1.17. These values are relatively close with a percent difference of 75%.
