What two factors are multiplied together to calculate total magnification in microscopy?

The total magnification in microscopy is determined by multiplying the magnification power of the eyepiece (ocular lens) by that of the objective lens being used. The eyepiece typically has a fixed magnification (commonly 10x), while objective lenses come in various magnifications (e.g., 4x, 10x, 40x, 100x).

When these two magnifications are multiplied, the resulting value indicates how much larger the specimen appears through the microscope compared to its actual size. For instance, if you have an eyepiece magnification of 10x and an objective lens magnification of 40x, the total magnification would be 400x. This is crucial for biologists and researchers who analyze microscopic structures, as it allows them to observe details that are not visible to the naked eye.

Other options do not correctly represent the components necessary for calculating total magnification. Light intensity is important for visibility but does not affect magnification, and factors like light wavelength and cell size do not play a direct role in determining the magnification provided by the microscope.
