Lab 14 – How big are the objects when viewed on the scope
Submit to Lab 14 dropbox as Lab 14-week10_LastName_FirstInital
When looking down the microscope through the ocular lens you see the ruler at 40X magnification
Count the number of mm spaces you can see and put that number here ____________
That number is the FOV measurement at 40X magnification
You will now use the formula listed below in results to calculate the FOV for 100X, 400X and 1000X total magnifications.
|FOV calculations||FOV in mm||FOV in mm|
|4X -measured (M1)||D1 =|
|100X -calculated*(M2)||D2 =|
|400X -calculated*(M3)||D3 =|
|1000X – calculated (M4)||D4 =|
To get 100X FOV use the formula M1*D1=M2*D2
Solve for D2
To get 400X FOV use the formula M1*D1=M3*D3
Solve for D3
To get 1000X FOV use the formula M1*D1=M4*D4
Solve for D4
Show your math
What happens to the FOV as total magnification increases?
The prokaryotic organism Staphylococcus aureus measures 1 mm in diameter how many bacteria lined up across the diameter of the 1000X total magnification would fit?
The eukaryotic organism Paramecium measures 1 mm in length how many organisms lined up across the diameter of the 1000X total magnification would fit?
Hint think about size of object.
