Answer:
We would not be able to make our way around the earth's surface, to read, to sculpt or to create technology because we cannot see!
Explanation:
The minimum angular separation that can be distinguished by an eye gives the angular resolution of the eye.
Given that the Angular resolution with infrared radiation is = [tex]1.0^0[/tex] equal to [tex]60'[/tex]
This resolution is very much greater than that of the eye [tex](1')[/tex]
The angular resolution that our eyes can see is about [tex]\frac{1}{3}mm[/tex] at arms length
Angular resolution of infrared = [tex]\frac{1}{3} * 60 = 20mm[/tex] at arms length
We therefore cannot read, sculpt or create technology because we cannot see.
