    it is very simple as the ray is passing through the lens twice and interacting with the mirror once. so simple

  • Neeraj bansal best-answer

    Rays are first getting refracted from lens and then they are being reflected from mirror which is placed behind the lens and because of this they are coming back towards lens and are again getting refracted. Thats why he has taken focal length of lens twice and that of mirror once.
