Show your working.Using the scanning (4x) objective and the metric ruler, record the number of millimeters you see along with the letter “e.” Your value: 2 millimeters Convert the figure you attained to micrometers (1 millimeter = 1,000 micrometers). This is the diameter of the field of view for the low-power objective (LPD). The field of view is the circular field you see when you look through the oculars. The field of view changes at different magnifications. Your value (LPD): 2,000 micrometers -please help me with the problem in the picture.
