A student is using a convex lens of focal length 10 cm to study the image formation by a convex lens for the various positions of the object. In one of his observations, he may observe that when the object is placed at a distance of 20 cm from the lens, its image is formed at (select the correct option)
-
20 cm on the other side of the lens and is of the same size, real and erect.
-
40 cm on the other side of the lens and is magnified, real and inverted.
-
20 cm on the other side of the lens and is of the same size, real and inverted.
-
20 cm on the other side of the lens and is of the same size, virtual and erect.
C.
20 cm on the other side of the lens and is of the same size, real and inverted.
Given, focal length of the image, f = 10 cm.
Thus, the object is placed at 2 F ( 2 x 10 = 20 cm). Hence, the image is also formed at 2F.
The image will be of same size as that of the object and is real and inverted.
