Task 2. Determination the value division of ocular grid of the biological microscope.
2.1. For the determination of value division of ocular grid ( 2.2. The value division of ocular grid is determined as ratio of diameter of the wire (it is known from the task 1) to the number of divisions that cover the wire along the diameter: 2.3. Put the results of measurements and calculations to the table 2.

) it is necessary to determine the number of the smallest (noc.) divisions corresponding to the thickness of wire with unknown diameter (d).
