In Fig. 33-52a, a beam of light in material 1 is incident on a boundary at an angle of θ1 = 30°.The extent of refraction of the light into material 2 depends, in part, on the index of refraction n2 of material 2. Figure 33-52b gives the angle of refraction θ2 versus n2 for arrange of possible n2 values. The vertical axis scale is set by θ2a = 20.0° and θ2b = 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 n2 = 2.4, then what is angle θ2?
