Final answer:
The minimum separation, d, between two objects on the ground that can still be distinguishable at a wavelength, λ, can be determined by the formula d = n×h×D.. Substituting the given values into this formula, the minimum separation is approximately 21.726 meters.
Step-by-step explanation:
The minimum separation, d, between two objects on the ground that can still be distinguishable at a wavelength, λ, can be determined by the formula d = n×h×D.
Using the given values:
- h = 7300 m
- D = 2.2 mm = 0.0022 m
- n = 1.35
- λ = 721 nm = 0.000721 m
Substituting these values into the formula, we have: d = 1.35 × 7300 × 0.0022 = 21.726 m
Therefore, the minimum separation, d, between the two objects on the ground is approximately 21.726 meters.
