1) Comea Pupil - Aqueous chamber - Retina
2) Conjunctiva Corea - Vitreous chamber Retina
3) Comea - Pupil - Biconvex lens - Retina
4) Iris - Pupil - Comea Retina​

Answer 1

option 3 is the right answer.

Answer 2

Identify the correct sequence of organs of eye that focussing the light onto the retina.

1) Cornea Pupil - Aqueous chamber - Retina

2) Conjunctiva Cornea - Vitreous chamber Retina

3) Cornea - Pupil - Biconvex lens - Retina

4) Iris - Pupil - Cornea Retina​

Answer - Correct sequence of pathway of light is - 3) Cornea - Pupil - Biconvex lens - Retina.

•Cornea is the transparent part of eye covering iris and pupil. It performs function of refracting light.

•Pupil is the hole in the eye which helps passage of light. It is on the iris and controls amount of light entering the eye by dilating or constricting.

•Lens is the part of eye which actually focusses the light on retina. It is flexible in nature.

•Retina is the part found at back of eye. It contains photoreceptors namely rods and cones. Retina sends visual signals to brain via optic nerve.
