(a) : Magnification of compound microscope is not connected with numerical aperature. The magnifying power is represented by the symbol 'X'. The total magnification of a microscope is obtained by multiplying the objective magnification and ocular lens magnification e.g., if the magnifying power of an ocular lens is 10X and of the objective is 40X, then the total magnifying power of a microscope is 10×40=400X.
