In the above figures f is located at the focal


point of the lens. Which statement are true?





A) The lens in Fig. b is a converging lens.


B) An object placed to the left of f and the lens in Fig. a produces a virtual image.


C) An object placed to the left of f in Fig. a results in an image on the right side of the lens.


D) An object placed to the left of f in Fig. b results in an image on the left side of the lens.


E) An object placed between f and the lens in Fig. a produces a virtual image.


F) An object placed between f and the lens in Fig. a results in an image on the left side of the lens.


G) An object placed to the left of f and the lens in Fig. b produces a virtual image.

Physics - converging %26amp; diverging lens?
A) wrong %26gt;%26gt; fig b %26gt;%26gt; concave or diverging lense





B) wrong %26gt;%26gt; object placed to the left of f in convex lens produces REAL/INVERTED image.





C) TRUE





D) TRUE


concave lens %26gt; only forms image on right side when placed within focus





E) true





when object comes inside the focal length %26gt;%26gt; image is virtual and errect. image is on the object side (magnified)





F) true %26gt;%26gt; reasoned in (E)





G) true for concave lens
