The angular resolution of a $10 cm$ diameter telescope at a wavelength of $5000 \overset{˚}{A}$ is of the order of:

Options:

Answer:

Solution:

Here $R \cdot P . = \frac{1}{Δ θ}$ $∴ Angular resolution Δ θ = \frac{1.22 λ}{D} = \frac{1.22 \times 5000 \times 1 0 ^{- 10}}{0.1} = 6.10 \times 1 0^{- 6} ≅ 1 0^{- 6}$
