- 7:47 a). You make of plot of sin(0¡nside) versus sin(0outside). What is the index of refraction for the prism if the slope of the best fit line is 0.647 ± 0.004? b) . If your lab partner calculates the index of refraction of a medium to be 1.3 ± 0.6, determine the speed of light as it travels through the medium. Assume the speed of light in vacuum is 3x10® m/s. c) You now orient the prism with respect to the light as shown below. Which color will get refracted the most? Least? Explain. (Top View)How do I find the following with the data provided: Refractive index of acrylic, Speed of light through acrylic,Refractive Index (n) is a ratio of the speed of light in a vacuum to the speed of light in materials such as glass, water, plastic, etc. Using Snell's Law, and given an air to glass interface with and angle of incidence of 15 degrees, what will be the angle of refractance R if the refractive index of the glass is 1.5 ?
