If you focus the image of a distant object, whose shape is given below, on a screen using a convex lens, the shape of the image of this object on the screen would be:
(a)
(b)
(c)
(d)
उत्तर
As the image is focused on the screen thus the image formed is real. And, we know that real images are always inverted.
Thus, the shape of the image of the given pattern is represented by figure (b).
Hence, the correct answer is
