Total magnification on a microscope is calculated by multiplying the magnification power of the objective lens by the magnification power of the eyepiece (ocular lens). For example, if you are using a 10x eyepiece and a 40x objective lens, the total magnification would be:
Total Magnification = Eyepiece Magnification x Objective Magnification
Total Magnification = 10x x 40x = 400x
This means that the specimen being viewed is magnified 400 times its actual size. It’s important to note that the eyepiece simply helps to enlarge the image created by the objective lens, and both components work together to provide a clearer and more detailed view of the specimen.
