Study the ray diagram of an object placed in front of a lens. (i) Write three characteristics of the image formed? (ii) In which position of the object will the magnification be – 1?

From the ray diagram, the image formed is real, inverted, and diminished because the object is placed beyond 2F₁ of a convex lens.

    1. (i) From the ray diagram, the image formed is real, inverted, and diminished because the object is placed beyond 2F₁ of a convex lens.

      (ii) The magnification will be –1 when the object is placed at 2F₁, as then the image is formed at 2F₂, real, inverted, and of the same size as the object.
