Question

The wavelength of ray incident on
a telescope is 6000 Å and aperture
of objective is 5:0 metre. Find the
angular limit of resolution of the
telescope.
​

Answer 1

Answer :

=> 2.9 × 10⁻⁷ radians.

Step by Step Explanation :

Hey Mate,

Given,

Diameter = 100 inch  = 2.54 m

λ =6000 Angstrom = 6 × 10⁻¹⁰ m

Limit of resolution = $\frac{1}{\theta}=\frac{D}{1.22λ}$

=> $\frac{2.54}{(1.22 *6 *10^{-10} )}$

=> 2.9 × 10⁻⁷ radians.
