MCQ
An image is formed on the retina. This is due to:
  • A
    Successive refraction at the retina.
  • B
    Successive refraction at the cornea.
  • C
    Reflection at the cornea.
  • D
    Reflection at the retina.
✓

Answer

  1. Successive refraction at the cornea.

Explanation:

The lens of the human eye is biconvex. When we see an object, the light rays from the object get refracted and as a result of that the image will focus on the retina. The image thus formed is real and inverted. This image is carried to the brain in the form of electrical signals by the optic nerve.
