Diameter of human eye lens is 2 mm2 \mathrm{~mm}. What will be the minimum distance between two points to resolve them, which are situated at a distance of 50 m50 \mathrm{~m} from eye. The wavelength of light 5000 A˚Å.

Options

  1. A2.32 m2.32 \mathrm{~m}
  2. B4.28 mm4.28 \mathrm{~mm}
  3. C1.25 cm1.25 \mathrm{~cm}
  4. D12.48 cm12.48 \mathrm{~cm}

Correct answer

C. 1.25 cm1.25 \mathrm{~cm}

Step-by-step solution

For the aparture, limit of resolution yD≥λd\Rightarrowy≥λDdy≥5×10−72×10−3×50≥1.25 m\begin{aligned}& \frac{y}{D} \geq \frac{\lambda}{d} \Rightarrowy \geq \frac{\lambda D}{d}\\ & y \geq \frac{5 \times 10^{-7}}{2 \times 10^{-3}} \times50 \geq 1.25 \mathrm{~m} \end{aligned}
