The following are parts of the eye

  • Retina
  • Pupil
  • Iris

The correct equivalent in the same order are

  • A. Diaphram, Aperture, Film
  • B. Aperture, Diaphram, Film
  • C. Film, Diaphram, Aperture
  • D. Film, Aperture, Diaphram




Let’s analyze each of the parts as follows:

  1. The retina is the part of the eye where images are formed, it functions like the photographic film where the images of a camera gets formed and recorded.
  2. The pupil is a small opening at the center of your eye, it is surrounded by the bigger black ball called iris. This small opening allows light to enter into the eye for image formation. A similar opening in the camera is the aperture.
  3. Iris is the layer of muscle surrounding the small opening called pupil, it controls the opening and moderates the amount of light entering through this opening. The diaphragm does the same job in a camera.

Now for the right answer to the above question:

  1. Option A is incorrect.
  2. Option B is incorrect.
  3. C is incorrect.
  4. D is the correct answer.


You may please note these/this:

  • The functionality of the eye is similar to that of a camera, with different parts sharing similar roles.
