Two converging lenses of the same focal length f are separated by a distance 2f. The axis of the second lens is inclined at angle theta=60^@ with respect to the axis of the first lens. A parallel paraxial beam of light is incident from left side of the lens. Find the coordinates of the final image with respect to the origin of the first lens.
