To calculate the total magnification of a microscope, you simply multiply the magnification of the ocular lens by the magnification of the objective lens. In this case, the ocular lens magnification is 10x, and the objective lens magnification is 40x.
So, the calculation would be:
Total Magnification = Ocular Magnification x Objective Magnification
Total Magnification = 10x x 40x = 400x
This means that the specimen is being magnified 400 times its original size. Understanding total magnification is crucial for analyzing specimens accurately in microscopy.
