by which the ray turns (comparing the direction of propagation before and after the reflection) is δθ θ 2 180 2 r . The final contribution is the refraction suffered by the ray upon leaving the sphere: 3 = ir again. Therefore, dev 1 2 3 180 2 4 . =++=° +− (b) We substitute θθ r n i = sin ( sin ) 1 1 into the expression derived in part (a), using the two given values for n . The higher curve is for the blue light. (c) We can expand the graph and try to estimate the minimum, or search for it with a more sophisticated numerical procedure. We find that the dev minimum for red light is 137.63° 137.6°, and this occurs at i = 59.52°. (d) For blue light, we find that the
