- The first medium is air and the second medium is Mystery B. Air has a measured index of refraction of 1.003 but will be taken as having n=1. So, Snell's law reduces to n2=sin01/sin02. From the data and the graph, what is the slope of the line? Then, use Snell's law and the slope value to determine the refractive index of the given material (Mystery B). Record the calculated index of refraction.A 3.87 m long pole stands vertically in a lake having a depth of 2.07 m. When the Sun is 38.2o above the horizontal, determine the length of the pole's shadow on the bottom of the lake. Take the index of refraction for water to be 1.33.Building contractors often install double-glazed windows to prevent thermal energy (heat) from entering or exiting a building. In addition to being effective insulators, such windows present interesting optical effects. 62.0 mm In the figure, a double-glazed window consists of two identical of glass (ng panes 1.54), each yg thick, separated by an air gap of ya = 49.6 mm.
