Question

What is the nature of the image formed on the retina of the human eye of an object?
(A)Virtual and erect
(B)Virtual and inverted
(C)Real and erect
(D)Real and inverted

Answer 1

The retina is a delicate layer of tissue that lines the back of the eye on the interior. It is placed near the optic nerve. The motive of the retina is to collect light that the lens has focused, change the light into neural signals, and send these signals on to the brain for visual contrast.

Complete answer: Option (A)Virtual and erect: The images that are constructed when the light rays appear to join at a definite point after the reflection from the mirror is known as a virtual image.
An erect image is the one that seems right-side-up. It is established due to the actual crossing of light rays, unlike the virtual image. Erect image shows the directions are the same as those in the object.
Option (B)Virtual and inverted: Not possible at all.
Option (C)Real and erect: A real image is inverted, it is an image which is organized in the plane of convergence for the light rays that arise from a provided object, a real images can be induced by concave mirrors and converging lens if the object is spotted distantly away from the lens than the focal point.
Option (D)Real and inverted: The eye lens is convex and develops real and inverted images and when the object is held before the focus point and the middle of the lens it forms virtual and erect images. The images shaped on the retina are real and inverted and further, the message brought by the optic nerves by chemical impulses to the brain, which changes them into erect images that we watch with our eyes.
Hence option D is correct.

Note: An image is designed on the retina with light rays converging most at the cornea and upon reaching and departing the lens. Light from the top and bottom of the object is designed and creates an inverted real image on the retina.
