STUDY OF LAW OF REFRACTION OF LIGHT Top Material: Air Top Index of Refraction (n): Bottom Material: Water Bottom Index of Refraction (n): 1. Flash the light at certain angle so that light gets refracted and passes from one medium to another medium. Do it for 5 different incident angles. Use the equations n sin 8. = n2 sin 62 Use the equation to predict for 62 = sin-1(* sin 6) 2. After you complete the predictions, you can observe using the protractor and provide the observed refracted angle.

Based on your data in the data tables, what patterns do you observe? Write at least three summary statements. Total Internal reflection: Flash the light at certain angle so that light gets refracted and passes from one medium to another medium with refracted angle is 90°. Use the equations n sin 8. = n2 sin 82 Use the equation to predict for 0, = sin-2 sin oz) = ** 121 When you plug 02= 90, corresponding value for is called critical angle. When you increase the incident angle, the ray undergoes total internal reflection. Predict the critical angle for the following condition and check the predicted angle using the simulation. Make sure to provide necessary screen shot here. 1. Glass - water interface (rays pass from Glass to Water) Predicted for critical angle = @c = 2. Glass - air interface (rays pass from Glass to air) Predicted for critical angle = 8c = 3. Water to air interface (rays pass from Water to air) Predicted for critical angle = @c = After you complete the predictions, you can observe using the protractor and provide the observed refracted angle.

Discussion questions: Is it possible for total internal reflection if light passes from air to Glass, why or why not? Provide answer with reasons:
