Options
- Athe aperture of the pupil
- Bthe distance of the object from the eye
- Cthe size of the image produced on the retina
- Dthe true size of the object
Correct answer
C. the size of the image produced on the retina
Step-by-step solution
The perceived size of an object depends on the visual angle subtended by the object at the unaided eye.
The visual angle directly determines the size of the image formed on the retina. A larger visual angle results in a larger image on the retina, making the object appear larger.
Therefore, the perceived size of an object by an eye is primarily determined by the size of the image produced on the retina.
