How is total magnification calculated?

Total magnification is calculated by multiplying the magnification of the objective lens by the magnification of the eyepiece lens. This method combines the power of both lenses to determine the overall enlargement of the specimen being observed.

For example, if the objective lens has a magnification of 40x and the eyepiece lens has a magnification of 10x, the total magnification would be 40 x 10 = 400x. This formula is crucial in microscopy because it allows users to achieve a higher level of detail when examining samples, making it an essential concept for anyone working in a medical laboratory or conducting microscopic analysis.

The other options suggest incorrect methods for calculating total magnification, such as division or addition, which do not account for how these lenses work together to form a complete image.
