Question

Assume that light of wavelength $600 nm$ is coming from a star. The limit of resolution of telescope whose objective has a diameter of $2 m$ is :

Accepted Answer

$	heta_R = 1.22 \frac{\lambda}{d}$; $\lambda = 600 	imes 10^{-9} m$, $d = 2 m$. $	heta = \frac{1.22 	imes 600 	imes 10^{-9}}{2} = 3.66 	imes 10^{-7} rad$
