Answer #1
  • Focussing of light on retina is a combine efforts if many structure in eyes
  • The main structure are the cornea and lens.
  • The light Hit the eyes at different angles what ever the angle be our cornea bend it to an angle .
  • This light bend by cornea hit the lens and theens along with viteihs humor that is filled in the posterior chamber of eye and it reach the retina
  • This when reach retina will cause the transformation of image into electric impulses and will be seen by optic nerve .

How is it possible that our eye allows sharp image formation from both distant and nearby objects? a. The refractive index of the cornea changes depending on how far the viewed object is. b. The shape of the lens changes between close-up and distant viewing, focusing the light on the retina. c. The muscles surrounding the eye can contract or relax, slightly changing the shape of the eye and thus allowing the incoming light to be focused on the retina...

The pupil (the opening through which light enters the lens) of a house cat's eye is round under low light but ciliary muscles narrow it to a thin vertical slit in very bright light. Assume that bright light of wavelength 560 nm is entering the eye parallel to the principal axis of the lens and that the pupil has narrowed to a slit that is 0.500 mm wide. What are the three smallest angles on either side to the central...
