(c) Similarly, we find that the second-order θdevminimum for blue light (for which n= 1.343) is 233.48°233.5≈°, and this occurs at i= 71.52°. (d) The difference in devin the previous two parts is approximately 3.1°. (e) Setting k= 3, we search for the third-order rainbow angle numerically. We find that the devminimum for red light is 317.5°, and this occurs at i= 76.88°. (f) Similarly, we find that the third-order devminimum for blue light is 321.9°, and this occurs at i= 76.62°. (g) The difference in devin the previous two parts is 4.4°. 72. (a) The first contribution to the overall deviation is at the first refraction: δθ1=−ir. The next contribution(s) to the overall deviation is (are) the reflection(s). Noting that the angle between the ray right before reflection and the axis normal to the back surface of the sphere is equal to
