Problem: Two light bulbs are 1.0m apart. From what distance can these light bulbs be marginally resolved by a small telescope with a 5.0cm -diameter objective lens? Assume that the lens is limited only by diffraction and λ = 600nm

FREE Expert Solution

The resolving distance, x, is given by:

x=1.22λDd

Diameter, d = 5.0 cm(1m/100cm) = 0.05 m

Resolving distance, X = 1.0 m
