Question 408: Waves Optics

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

Limit of Resolution for a Telescope is
$$	heta  = 1.22{\lambda  \over d}$$
Given, $$\lambda $$ = 600 $$ 	imes $$ 10
-9
; d = 2 m
By substituting the values, we get
$$	heta $$
 = 3.66 $$ 	imes $$ 10
