Question

The image of an object which cannot be obtained on a screen is called:
A) Enlarged image
B) Real image
C) Virtual image
D) Inverted image

Answer 1

Hint: Here we have to examine each of the options one by one to get the answer.
Images are either formed by a lens or mirror. The lens and mirror might be converging or diverging.

Complete step-by-step answer:
Enlarged image:
An enlarged image is an image greater than the object
Only the convex lens forms an object's enlarged and virtual image while the object is positioned between the focal point and the optical core.
Real image:
Real Images are images that can be found on the screen. They are created when the light rays, after being absorbed from the mirror, finally meet at a point.
The real image is reversed with respect to the object.
Virtual image:
Virtual Images are images that must be found in a mirror and which cannot be seen on the screen. They are created as light rays start to intersect at a point after they have been absorbed from a mirror. A virtual image is erected with respect to the object.
Inverted image:
In an optical device, an image, either actual or visual, that has a vertical orientation opposite to that of an object, i.e. an image that is upside down relative to an object's orientation. The image that reflects specifically on the retina of the eye is an inverted image.
Therefore, a true and reversed image can be obtained on the screen. Furthermore, depending on the optical instrument used, the original and inverted image can be enhanced or decreased, which means that true, inverted and enlarged images can be obtained on the screen.

Hence, option C is correct.

Note: Hence, in short we can say that virtual images cannot be obtained on the screen because the image is created by light rays that do not intersect nor seem to intersect as they are generated backwards.
