Answer to Problem 5P
The diameter of pupil of human eye needed to see the same resolution in the infrared at wavelength of
Explanation of Solution
The diameter of pupil of human eye is
Write the expression for angle of separation between two objects according to the criterion for resolution.
Here,
Since the person need to see the same resolution in the infrared as in visible the angle of separation in both region of light can be equated.
Using equation (I), equation (II) can be modified as,
Solve equation (III) for
