The minimum distance from the eye at which an object appears to be distant is:
Correct answer: A. 25 cm
- A. 25 cm
- B. 22 cm
- C. 35 cm
- D. 20 cm
Explanation
This is approximately 25 cm from the eye. The normal human eye can focus a sharp image of an object on the eye if it is located anywhere between infinity and a point known as the near Point.

About Optics
Light is studied through reflection, refraction, dispersion, interference, diffraction and polarization, linking ray behavior with its wave nature. Questions may involve mirrors, lenses, optical instruments, refractive index and image formation, while geometrical optics deals with rays and wave optics explains effects such as interference and diffraction.
