Previous question: The field of view is the maximum area visible through the lenses of a microscope, and it is represented by a diameter. To determine the diameter of your field of view, you can place a transparent metric ruler under the low power (10X) objective of a microscope. You would focus the microscope on the scale of the ruler and measure the diameter of the field of vision in millimeters. Refer to the image taken of this preparation below. What is the approximate field of view as seen by this 10X objective. Note: This microscope has a 10X eyepiece, giving a total magnification of 100X. The image shows the 1mm is for this question. - Answer for this question was 3mm.
