Cal Culator is preforming experiments to determine the index of refraction of two unknown materials. Cal determines that the light follows the paths as shown on the diagrams below. Use this path, a protractor, a calculator, qnd Snell's law to determine the index of refraction of the unknown material. Show all your work in the space beside the diagram.
