A student wants to set her compound light microscope to a total magnification of 100x. The ocular lens is 10x.
Question
A student wants to set her compound light microscope to a total magnification of 100x. The ocular lens is 10x.
Solution
The student needs to use an objective lens of 10x magnification. The total magnification of a compound light microscope is calculated by multiplying the magnification of the ocular lens by the magnification of the objective lens. In this case, the ocular lens has a magnification of 10x. Therefore, to achieve a total magnification of 100x, the student should use an objective lens of 10x (because 10x (ocular lens) * 10x (objective lens) = 100x (total magnification)).

To make a compound microscope you can add a 2nd lens to the simple magnifier arrangement. The magnification produced by the objective lens (m) is multiplied by the magnification of the simple magnifier (Me), so the total magnifying power (MP) is increased. That is: MP = m Me.Calculate how far away from the objective lens you need to place the object to be viewed to produce a magnifcation of m = - 20, if the focal length of the lens is fo = 10.5 cm. Give answer to 3 significant figures.
In a compound microscope, the focal length of objective lens is 1.2 cm and focal length of eye piece is 3.0 cm. When object is kept at 1.25 cm in front of objective, final image is formed at infinity. Magnifying power of the compound microscope should be:
