Question 427: Wave Optics

Question

The angular resolution of a 10 cm diameter telescope at a wavelength of 5000 $\mathop A\limits^ \circ  $ is of the order of

Accepted Answer

The angular resolution,
$\Delta $$	heta $ = ${{1.22\lambda } \over D}$
= ${{1.22 	imes 5000 	imes {{10}^{ - 8}}} \over {0.1}}$
= 6.1 $ 	imes $ 10
-4
$ 	herefore $ Order = 10
