Question

My lab partner and I were unable to finish our lab, and do not have access to the microscopes necessary to do so. We are hoping to find answers to any questions unanswered in the picture, thank you!

Focus on your thumb nail using the hiswectom microscope. With the ruler, measure the width in millimeters (mm) of your thumb at the widest point of your nail. 3. To calculate the diameter of high power field (40X) complete these two steps: a. divide the magnification of the high power field by the magnification of the low power field: b. then divide the diameter (of the low Review questions: powfiel (um) (CAnswer in question 2) by the quotient (3a) 1.

Using the dissection microscope measure the diameter of the field with the lowest magnification using a millimeter ruler. What the maximum diameter of the field of view in millimeters (mm)?

Explanation / Answer

Procedure compound microscope:

4. Length of Paramecium: 195

Width of paramecium: 60

Procedure: Dissection microscope:

1. 24 mm

2. 7.5 mm

3. 10 mm

Review questions:

2. The accuracy increases due to higher resolution at higher magnification. (Definition of resolution: Ability to distinguish 2 adjacent point clearly.)

3. Field of viewnew =  Field of viewold*Magnificationold/Magnificationnew

Field of view at 5X = 2 mm * 10X / 5X = 4 mm

4. Field of view at 50X = 2 mm * 10X / 50X = 0.4 mm
