    Question focal length of the convex mirror

    # A convex lens forms a real image of a point object placed at a distance of 0.5 m from it. The image is also at a distance of 0.5 m from the lens. Midway between the lens and the image, a convex mirror is placed. It is found that there is no parallax between the object and its image. What is the focal length of the convex mirror?

    I give up.... what is it?

    In other words, at least try to explain your reasoning, or attempted reasoning before posting your homework problems on a forum. You're new, we have no reason to believe this is anything other than attempting to get your homework answered for you. I sincerely hope no one helps you until you start to help yourself a bit.
