The magnification of the ocular lens of a microscope is x10 and the magnification of the objective lens for low, medium, and high power are 4X, 10X, and 40X, respectively.
To estimate the size of an object seen with a microscope, first estimate what frac-tion of the diameter of the field of vision that the object occupies. Then multiply the diameter you calculated in micrometers by that fraction.

calculate total magnification use the formula: magnification = size of image size of real object measure the size of cells. Introduction Most cells are very small and can only be seen through a microscope. The cell image that you see through the microscope will be much larger than the object
On your worksheet below calculate the total magnification for each ocular/objective combination on your microscope. List the magnification for each objective on your microscope below.
Calculating Magnification Magnification is the number of times larger an image is compared with the real size of the object. In order to calculate magnification you need to divide the size of the image by the actual size of the specimen. You also need to rearrange the equation. Putting it in a triangle helps. Worked Example
The three images below show a worked example of how to calculate sizes of cells organelles from electron micrographs step by step. Follow these steps carefully then complete the calculations on the worksheet. Try to calculate the magnification of this pollen grain. This image shows a worked example.
