Q. The image formed on the eye retina is
Solution:
Solution:
The vitreous chamber in the eye is filled with vitreous humor, a gel-like fluid that is present at the back of the eye. The cornea focuses the image through the lens which is received by the retina and converts it into electrical signals and sends it to the brain via the optic nerve.
About 2/3rd of the power of the eye is provided by the cornea. While travelling, speed of light changes considerably. The remaining power required to produce an image is provided by the lens.
It is because of the refractive indices that the rays bend and curve. Convergence of the rays result in the formation of a real image. Divergence of the rays, result in the formation of a virtual image.
The image formed in the human eye is similar to the one produced by a single convex lens. It is because of the process of refraction and the curvature of the lens, the rays of light hit the lens, bend and the image is flipped. Furthermore, when this image hits the retina, it becomes inverted. A real, inverted image is produced when the rays from the top and bottom of the object converge
