The angular resolution of a 10cm diameter telescope at a wavelength of 5000Å is of the order of :

A

106 rad

B

10-2 rad

C

10-4 rad

D

10-6 rad

Answer

10-6 rad

Explanation

Solution

Using dθ=1.22λD=1.22×5000×10−100.10d\theta = \frac{1.22\lambda}{D} = \frac{1.22 \times 5000 \times 10^{- 10}}{0.10}

=6.1×10−6rad=10−6rad= 6.1 \times 10^{- 6}rad = 10^{- 6}rad
