WebFor a low power 4x system, the numerical aperture is going to be very low, on the order of 0.05 to 0.1. In a medium power 40x system, it could be in the range of 0.5 to 0.8 and for a high power system, it can be as high as 0.9 or 0.95. As long as there is air between the objective and the sample, the numerical aperture can never exceed 1. WebConcept note-3: -The total magnification of a lens is calculated by multiplying the magnification of the objective lens with the magnification of the eyepiece. Therefore, the required magnification of the objective should be 40 X as, 40 X 10 = 400. Try yourself to solve below questions: CONCEPT QUESTION- 1 :
