Limit of resolution of telescope

\Theta =\frac{1.22 \lambda}{\Delta }

\lambda=500 nm\\ \Delta = 200 cm

\theta=\frac{1.22 \times 5 \times 10^{2} \times 10^{-9}}{2 \times 10^{2} \times 10^{-2}}

\theta=305 \times 10^{-9} radian


Option 1)

305 \times 10^{-9}\; radian

Option 2)

610\times 10^{-9}\; radian

Option 3)

152.5 \times 10^{-9}\; radian

Option 4)

457.5 \times 10^{-9}\; radian
