Question

Assume that light of wavelength 6000 A⁰ is coming from a star . What is the limit of resolution of a telescope whose objective has diameter of 100 inch

Open in App

Solution

here D = 100in = 2.54m

lambda =6000 angstrom= 6 ( 10^-10) m

putting the formula, 1/theta = D/1.22lambda

We get theta nearly equals to 2.9 (10^-7)radians.
