Answer:
Explanation:
The problem is based on the resolving power of the eye . For it the formula is as follows :
Resolving power = 1.22 λ / D , λ is wavelength of light and D is diameter of the eye.
Putting the given values
R.P = 1.22 x 557 x 10⁻⁹ / 5.39 x 10⁻³
= 126.074 x 10⁻⁶ radian
This is the minimum angular separation that can be resolved .
minimum linear separation that can be resolved = distance x angular separation that can be resolved
.683 = distance x 126.074 x 10⁻⁶
distance = .683 / 126.074 x 10⁻⁶
= 5417.5 m
= 5.417 km
Answer:
5.42 Km
Explanation:
