To calculate the total magnification of the compound light microscope multiply the magnification power of the ocular lens by the power of the objective lens. For instance, a 10x ocular and a 40x objective would have a 400x total magnification. The highest total magnification for a compound light microscope is 1000x.
| Total Magnification: | |
| To figure the total magnification of an image that you are viewing through the microscope is really quite simple. To get the total magnification take the power of the objective (4X, 10X, 40x) and multiply by the power of the eyepiece, usually 10X. | |

How is total magnification calculated quizlet?
The total magnification is calculated by MULTIPLYING the ocular lens magnification and the objective lens magnification.
What is the total magnification of a specimen using the 40x objective quizlet?
Total magnification is calculated by multiplying the ocular lens magnification by the objective lens magnification. What is the total magnification of a specimen using the 40X objective? total magnification is 400X.
What does 40x on a microscope mean?
A 40x objective makes things appear 40 times larger than they actually are. Comparing objective magnification is relative—a 40x objective makes things twice as big as a 20x objective while a 60x objective makes them six times larger than a 10x objective. The eyepiece in a typical desktop microscope is 10x.

What does 4x magnification mean?
Simply put, the “4” is the magnification power of the scope. If the magnification is 4x, it means your target will be magnified 4 times larger than what the naked eye sees. The singular “4” also indicates that this scope has a fixed magnification. This means that you can't zoom in and out with this scope.
What is the difference between 4x 10X and 40x on a microscope?
