The maximum magnification that can be obtained with a convex lens of focal length 2.5 cm is (the Ieast distance of distinct vision is 25 cm).

The power of a convex lens of focal length 25 cm is …………… .

Calculate the maximum magnifying power of a simple microscope consisting of a convex lens of focal length 5 cm . Distance of distinct vision is 25 cm .

Three thin lenses are combined by placing them in contact with each other to get more magnification in an optical instrement. Each lens has a focal length of 3 cm. If the least distance of distinct vision is taken as 25 cm, the total magnification of the lens combination in normal adjustment is
