Formation of image of an Eye
Formation of Image of an Eye
Formation of Image:
Light is bent by refraction at the cornea and the lens such that a sharp image is formed on the retina. The crystalline lens is made up of jellylike, fibrous substances that make it elastic. The cilliary muscles, to which the lens is attached, can alter the curvature and thickness of the lens.
The average of the refractive indices of the materials of the lens is about 1.396. The liquids in front of and behind the lens have a refractive index of about 1.336. When light enters the eye from air, most of the bending occurs at the cornea itself because of the sharp change in refractive index

8thMy experience with Abhyas is very good. I have learnt many things here like vedic maths and reasoning also. Teachers here first take our doubts and then there are assignments to verify our weak points.
