If a microscope has a 40× objective lens in place and a 15× eyepiece lens, the magnification of the system under these conditions is
To determine the magnification of a microscope system, you need to know the magnification of the objective lens and the eyepiece lens. The total magnification is calculated by multiplying the magnification of the objective lens by the magnification of the eyepiece lens.
In this case, the objective lens has a magnification of 40× and the eyepiece lens has a magnification of 15×.
To find the total magnification, you multiply the magnification of the objective lens by the magnification of the eyepiece lens:
Total magnification = Objective lens magnification × Eyepiece lens magnification
Total magnification = 40 × 15
Total magnification = 600×
Therefore, the magnification of the microscope system under these conditions is 600×.
