Webdifferentiate between the limit of resolution of the typical light microscope and that of the unaided human eye. for any light microscope, the limit of resolution is about 0.2 μm, any objects closer would not be seen as two distinct objects. The unaided human eye cannot distinguish two objects past 200-250 μm apart. WebThe resolution of a microscope or lens is the smallest distance by which two points can be separated and still be distinguished as separate objects. The smaller this value, the higher the resolving power of the …

Webθ = 1/2 angle of the cone of light entering the objective lens As d decreases, resolving power increases. This equation for resolving power applies to any kind of lens (telescope, camera, microscope, eye, etc.), but it assumes certain conditions of illumination that are not automatically met when a lens is used as a microscope objective.
