What type of image is formed on the retina of the human eye?
The image formed on the retina of the human eye is a real and inverted image. Light rays entering the eye converge onto the retina, where they form a small, inverted image of the visual scene, triggering neural signals that are interpreted by the brain as the visual perception of the external world.

The image formed on the retina of the human eye is a real and inverted image (A). When light enters the eye through the cornea and lens, it refracts and converges to form a focused image on the retina, which is located at the back of the eyeball. This image is inverted, meaning that the top-to-bottom and left-to-right orientations of the object are reversed on the retina compared to the actual object. Despite being inverted, this image is real because it can be captured and detected by the photoreceptor cells (rods and cones) in the retina. These cells convert light energy into electrical signals, which are then transmitted via the optic nerve to the brain for processing and interpretation. The brain reconstructs the visual information received from both eyes into a coherent, upright perception of the external world, allowing humans to perceive their surroundings accurately. Thus, the human eye forms a real and inverted image on the retina, crucial for visual perception and interpretation.
