2. You have a bi-convex lens, which has a refractive index of 1.55, a diameter of 2.54 cm, and both surfaces have equal magnitude radius of curvature. Using it, you create an image 50 cm behind the lens of an object a distance L in front of the lens. You can also use it to create an image a distance 1.75 behind the lens of an object a distance 25 em in front of the lens. a. Find the magnitude of radius of curvature of the surfaces. (20 pts) b. For the first imaging configuration described above, if you used 532 nm light, what would be the minimum spacing of two points on the object which could be resolved as distinct points in the resulting image?
