Index of Refraction Lab The objectives of this Lab are: -Tc verify Snell's Law. -Tc determine the refractive index of mystery material (m). -Tc find the speed of light in that mystery material (gm). Results Table 1. Angle of Incidence vs. Angle of Refraction Angle of incidence {91) () Angle of refraction (9r) () Table 2. Angle of Incidence vs. Angle of Reection Angle of reection (9!) () Angle of incidence {90 () Angle of refraction (Br) 1. Using the calculator to find amid sing; and complete Table 1 Note: Be sure the angle unit in the calculator is in degree (DEG) instead of radians (RAD). 2. Using Excel, plot WG-axis) vs. W-axis) Copy from Excel and paste the nal graph in this document. 3. Using Excel to determine the equation that correlates these variables and write the equation in the rectangle using the appropriate variables. (Experimental Equation) Read the following information and answer the next two questions. \"mystery _ SERGI- Hair 5m 6T According to Snell's la_ml__i.f am; 1 for index refraction of air, we obtain sin. 81- 71 : mystery sin 9.. , Solving for sinlfl== 5m 65 = \"mystery 51'316,. (Theoretical Equation) 4. Comparing the experimental and theoretical equations, what is the meaning of the slope of the graph sinliJs. sing 5. What are the units of the slope? 6. Calculate the experimental value of the speed of light in the mystery material (W. Show your work. C Remember 7} mystery . : = where c = 3.00 x 108 m! s l7 ' mystery Write below the experimental values of the index of refraction and the speed of light of the mystery material. W (experimental)= Mmkxperimental) = '3'. Use Table '11 of your textbook to determine the identity of the mystery material. Choose the material with the index of re'action that is closest to your experimental value. Search on the internet the theoretical value of the speed of the light in the mystery material. Write the information below: Wm (WM? mama): 8. How compare the experimental and theoretical values of: a) the index refraction of the mystery material b) the speed of light of the mystery material 9. From Table 2, what can you conclude about the incident and reection angles? 10. What happens with the reection (91') and refraction (9r) angles if the angle of incidence (90 is: a) 91;: 0 (explain why this happens) b) 8;: 90 (explain why this happens)
