A Cassegrain telescope uses two mirrors of radii of curvature 25 cm and 16 cm separated by a distance of 2.5 cm. The position of the final image of an object at infinity is
Show Hint
For optical systems with multiple components (mirrors or lenses), the image formed by the first component acts as the object for the second component. Be careful with sign conventions and the location of this intermediate object relative to the second component.
