Answer:
0.3067 m
Explanation:
Resolving power of a lens is given by the expression
R.P = 1.22λ / D
where λ is wavelength of light used, D is diameter of the lens
Substituting the data given
R.P in radian =
[tex]\frac{1.22\times550\times10^{-9}}{35\times10^{-2}}[/tex]
R P = 19.17 X 10⁻⁷ radian
If d be the minimum spacing between two objects on the ground that is resolvable by lens
[tex]\frac{d}{160\times10^3} =19.17\times10^{-7}[/tex]
d = 0.3067 m
