STUDY OF LAW OF REFRACTION OF LIGHT Top Material: Glass Top Index of Refraction (n): Bottom Material: Air 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, sine =n, sin@2 Use the equation to predict for 21 * i sin & 0, =sini 2. After you complete the predictions, you can observe using the protractor and provide the observed refracted angle
