Question
Please help.
In the above figures f is located at the focal point of the lens. For each statement select True or False. An object placed between f and the lens in Fig. a results in an image on the left side of the lens. An object placed to the left of f in Fig. b results in an image on the left side of the lens. An object placed to the left of f and the lens in Fig. b produces a real image. An object placed between f and the lens in Fig. a produces a virtual image. The lens in Fig. b is a diverging lens. An object placed to the left of f and the lens in Fig. a produces a virtual image. An object placed to the left of f in Fig. a results in an image on the right side of the lens.Explanation / Answer
(a)
true because virtual image for the convex lens is always on the same side of the object.
(b)
true. because, concave lens always gives a virtual which is on the same side of the object.
(c)
False. because the concave lens never forms a real image.
(d)
true. The convex lens forms a virtual image if the object distance is less tha the focal length.
(e)
true
(f)
False. Because, convex lens gives virtual images only for the object distances which are less than
the focal length. hence we get a real image.
(g)
true. because real images are always formed on opposite side of the object
