Answer:
angular resolution = 0.07270° = 1.269 × rad
greatest distance from the camera = 118.20 m = 0.118 km
Explanation:
given data
diameter = 0.50 mm = 0.5 × m
distance apart = 15 cm = 15× m
wavelength λ = 520 nm = 520 × m
to find out
angular resolution and greatest distance from the camera
solution
first we expression here angular resolution that is
sin θ = .......................1
put here value λ is wavelength and d is diameter
we get
sin θ =
θ = 0.07270° = 1.269 × rad
and
distance from camera is calculate here as
θ = .................2
I =
I = 118.20 m = 0.118 km
