Magnification Calculation Steps
To calculate the magnification of a light microscope, you need to multiply the power of the eyepiece by the power of the objective lens.When using a light microscope, knowing how to calculate magnification is essential for accurate observation of microscopic objects. The magnification of a microscope is determined by multiplying the power of the eyepiece by the power of the objective lens. This calculation allows you to determine how much larger an object will appear when viewed through the microscope.
For instance, if a microscope has an 8X eyepiece and 10X objective lens, you would calculate the magnification as follows:
Magnification = Eyepiece Power × Objective Lens Power
Magnification = 8X × 10X = 80X
This means that with this combination, the observed object will appear 80 times larger than its actual size. Similarly, if you were to use a 40X objective lens instead:
Magnification = Eyepiece Power × Objective Lens Power
Magnification = 8X × 40X = 320X
With the 40X objective lens, the observed object will appear 320 times larger than its actual size. Understanding how to calculate magnification in a light microscope is key to obtaining detailed observations of microscopic structures.
