RESOLVING POWER OF SMARTPHONE CAMERA LENS AND HUMAN EYE LENS

The resolving power of an objective lens is its ability to differentiate two lines or points in an object. The greater the value of the resolving power of an optical instrument the smaller the minimum distance between two lines or points that can still be distinguished[1].

EXPERIMENT -

If we draw two small circles on a white paper with a pen so that they are 0.1 centimeter apart from each other and look at the two points at close range, we will see that we will be able to understand the two circles differently but the farther we go from that paper , the more It will become blurry and we will not understand that they are two different circles but it will look like they are connected together i.e. as a single circle.In the picture the right side image is from large distance whereas the left side image is taken closely(see below)

Similarly, if we draw the circles 1 cm apart and look at them from a close distance, we will see that we can clearly understand the two circles differently but the farther we go from that paper , the circles will gradually become blurred and we will not realize that they are two different circles . Let, us consider that When the circles were .1 centimeter apart, then the distance up to which our vision is able to identify them as two different circles be X. Again, Let, us consider that When the circles were 1 centimeter apart, then the distance up to which our vision is able to identify them as two different circles be Y. Then Y> X , that is, the farther the circles are, the more distance it will be up to which we can identify them as two different circles..The right side image is for near distance and the left side image is from far .(see below)

We can also check the resolution power of the lens by using the same method with two parallel lines 1 mm apart and by measuring the distance up to which the two lines can be distinguished as two different lines.For our eye resolution power we can do the same.
