no.....first reflection is from concave mirror.....this img acts as object for the convex miror

 Discussion Forums -> This Post 0 points    (0    in 0 votes )   [?]

A convex and a concave mirror each of focal length f are placed co-axially. They are separated by 4f and their reflecting surfaces face each other. An object is kept on the principle axis at a distance x from the concave mirror such that the final image after two reflections, first on the concave mirror, is on the object itself. Find x in terms of f.

I'm getting the ans as  but its not the right ans.
