| Abstract: | Vernier is one of the basic instruments widely used in both physical laboratoryand factories. There are three types of frequenly used precision, They are 0.1 mm, 0.05 mm and0.02 mm. In my paper, based on the resolving power of naked eye, I give a quantitative analysison its minimum limit of 0.02 mm. |
