Module 5: Lesson 4 ASSIGNMENT This Module 5: Lesson 4 Assignment is worth 28 marks. The value of each assignment and each question is stated in the left margin. Lesson 4 Assignment: Refraction (1 mark) LAB 1. When light travels from a low-index medium (fast) into a high-index medium (slower), does the ray bend toward or away from the normal. Answer: The ray bends towards the normal when light travels from low index medium to high index medium. (1 mark) When light travels from a high-index (slower) medium into a low-index (fast) medium, does the light ray bend toward or away from the normal? Answer: When the angle is set to 45 degrees the ray bends away from the normal from high index to low index. (3 marks) LAB 2. Set up the Light Refraction simulation with two refractive layers. You will need to vary the refractive index for each layer and the angle of the light ray in order to complete Table 2. Select “Show Calcs” () to assist in recording angles. Get as close to the ?i as you can, but record the actual value that you use. Table 2: Refraction Data n1 ?in n1sin?? in n2 ? out n2sin?? out 1.20 45° 0.8485 1.40 37.31 0.8486 1.30 32° 0.6889 1.66 23.67 0.6664 1.45 45° 1.0253 1.23 55.29 1.0111 1.51 40° 0.9706 1.00 74.25 0.9625 1.65 45° 1.1667 1.80 38.94 1.1313 According to your data in Table 2, which two values are always equal to each other? Answer: According to my data, none of the values are always the same, but value one and value three both are fairly close to each other on the table. (4 marks) LAB 3. Use the Water Refractions diagram and the Ethanol Refractions diagram to gather data regarding water refractions and ethanol refractions. Record your data in the tables provided.

Plot a graph of sine angle of incidence versus sine angle of refraction. Plot a line for water and a line for ethanol. Calculate the slope of each line on this graph. If you find it easier, please complete on a separate sheet of paper and then scan it. You may simply insert your scan into this document or email it to me as a separate attachment. Answer: -71755175895 I hope I did this right, enjoy the graph
