Question 168: Waves Optics

Question

Assuming human pupil to have a radius of $$0.25$$ $$cm$$ and a comfortable viewing distance of $$25$$ $$cm$$, the minimum separation between two objects that human eye can resolve at $$500$$ $$nm$$ wavelength is :

Accepted Answer

$$\sin 	heta  = {{0.25} \over {25}} = {1 \over {100}}$$
Resolving power $$ = {{1.22\lambda } \over {2\mu \sin 	heta }} = 30\,\mu m.$$

Answer

$$100\,\mu m$$

Answer

$$300\,\mu m$$

Answer

$$1\,\mu m$$

Answer

$$30\,\mu m$$
