how is image formed by eyes?describe......
Answers
Answer:
The image is formed on the retina with light rays converging most at the cornea and upon entering and existing the lens.
The light rays coming from the object kept in font of us enter through the cornea of the eye, pass through the pupil of the eye and fall on the eye -lens.
The eye-lens is a convex lens, so it converges the light rays and produces a real and inverted image the object on the retina.
The image formed on the retina is conveyed to the brain by the optic nerve and give rise to the sensation of vision.
When the image falls on the retina, then these light sensitive cells get activated and generate electrical signals.
The retina sends these electrical signals to the brain through the optic nerve and give rise to the sensation of vision and image is formed.
