A) \[\text{1}{{\text{0}}^{\text{6}}}\text{rad}\]
B) \[\text{1}{{\text{0}}^{\text{-2}}}\text{rad}\]
C) \[\text{1}{{\text{0}}^{\text{-4}}}\text{rad}\]
D) \[\text{1}{{\text{0}}^{\text{-6}}}\text{rad}\]
Correct Answer: D
Solution :
Angular resolution\[=\frac{1.22\,\lambda }{d}\] \[=\frac{1.22\times 5000\times {{10}^{-10}}}{10\times {{10}^{-2}}}\] \[=6.1\times {{10}^{-6}}\] \[\approx {{10}^{-6}}rad\]
