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
