here one with my chemistry basics here next above electron microscope well this is a wonderful topic to study got a nobel prize in the year 1986 and again in the year 2017 the electron microscope was invented because of the drawbacks of light microscope one of the major drawbacks of light microscope is the phenomenon of diffraction limitation so let's try to understand what is in image form by the microscope and how it is affected by the phenomena of diffraction if you understand this it will be very easy to understand the working of an electron microscope so keep watching for example when light passes through a slit it gets too frakkin so what you see is a central maxima first-order minima first-order maxima and so on now we have a convex lens in between then the lens collects the refracted light and focuses it on a screen this results in the formation of the image of the slit so the i
