In Fig. 33-52 a , a beam of light in material 1 is incident on a boundary at an angle of θ 1 = 30°. The extent of refraction of the light into material 2 depends, in part, on the index of refraction n 2 of material 2. Figure 33-52 b gives the angle of refraction θ 2 versus n 2 for a range of possible n 2 values. The vertical axis scale is set by θ 2 a = 20.0° and θ 2 b = 40.0°. (a) What is the index of refraction of material 1? (b) If the incident angle is changed to 60° and material 2 has n 2 = 2.4, then what is angle θ 2 ? Figure 33-48 Problem 48.
