The minimum distance from the eye at which an object appears to be distinct is called
Correct answer: C. Least distance of distinct vision
- A. Great distance of distinct vision
- B. Normal distance of distinct vision
- C. Least distance of distinct vision
- D. None of these
Explanation
The correct answer is Least distance of distinct vision. This term defines the closest point at which the eye can focus on an object clearly, typically around 25 cm for a normal human eye. This is a standard concept in optics related to human vision. Great distance of distinct vision is incorrect as it implies a larger distance, which is not what is being described. Normal distance of distinct vision is not a standard term used in optics, making it incorrect. None of these is invalid as the correct term is indeed provided in the options.

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.
