A green lаser is аimed аt the surface оf a transparent blоck as shоwn in the Figure below. Fog is sprayed into the path of the beam to make it more visible. Angles of incidence and the corresponding angles of refraction were measured and the data is shown in Table 1 below. The data was not labeled correctly, and students are unsure which is the incident angle, and which is the refracted angle. Figure 1: This picture shows the experimental set up used to obtain the data in Table 1. It shows the green light from the laser being refracted at the surface of a transparent block. Table 1: The angles, θ1 and θ2 as measured from the normal to surface of the block are shown in Table below. θ1 ± 1⁰ θ2 ± 1⁰ 5 2 10 6 20 13 31 20 45 27 56 33 65 36 a. From the data, complete the following statement and explain your choice: θ1 is the angle of ________________ and θ2 is the angle of __________________. b. Using the data to create graph of to determine the refractive index of the transparent block. c. According to Snell's Law the ratio of the sine of the angle of incidence, θ1, to the sine of the angle of refraction θ2; . Use the slope of the graph and the fact that the refractive index of light in air is approximately 1 to determine the refractive index of the transparent block. Show your work to obtain the refractive index. d. The manufacture gives the index of refraction for this transparent acrylic block as 1.5. Calculate the percent difference between the refractive index value you determined, and the manufacturers published value.
