Ford produced Model Ts in this manner for three years at its new Highland Park plant before adopting the assembly line. When modern drivers think about the Ford Model Tâif they think about it at allâthey perhaps dimly perceive it as the car that changed the world.
The Cornea. The cornea represents the strongest part of the refracting power of the eye, providing about 80% of the power of the system. The index of refraction of the cornea is about 1.376. Rays pass from the cornea into the watery fluid known as the aqueous humor which has an index of refraction of about 1.336, so most of the refraction is at the cornea-air interface.
Cornea. The cornea and sclera form the outer fibrous layer of the eye. The cornea is a clear transparent tissue, which is located forward of the eyeball. Light rays pass through this limpid tissue, and on through the crystalline lens to reach the retina.The cornea is convex in shape and for this reason directs or bends light rays so that they can be focused on the retina.clera. The eye consists of three layers of tissue which make up the wall of the eye. The sclera is the outermost layer of tissue, also called the white of the eye. This layer is a very stable fibrous membrane that continues to retain the shape of the eye and provides protection.
