If a microscope"s ocular is marked 10x and the lower objective is marked 2x, what would be the total magnification when using the low power objective/
Would that be 20x?
To calculate the total magnification when using a microscope, you need to multiply the magnification of the ocular lens (eyepiece) by the magnification of the objective lens.
In this case, the ocular lens is marked as 10x, and the lower objective lens is marked as 2x.
To find the total magnification, multiply 10x (ocular) by 2x (objective):
Total Magnification = Ocular Magnification x Objective Magnification
Total Magnification = 10x x 2x
Total Magnification = 20x
Therefore, the total magnification when using the low power objective would be 20x.
