WebElectron microscopy is a valuable tool to obtain high-resolution images. The way that an electron microscope works is to accelerate a focused stream of electrons in a vacuum … WebAs the wavelength of an electron can be up to 100,000 times shorter than that of visible light, electron microscopes have a higher resolution of about 0.1 nm, which compares to about 200 nm for light microscopes. …
WebThe electrons can be focused by electro-magnetic lenses much like the light rays. Electron beam can vibrate like light rays but has very short wave length as compared to light rays. Wave length of electron beam λ = 0.005 nm as compared to 550 nm of visible light. Resolution increases with the decrease of wave length. WebSince it had been established in the 1920s that electrons have the properties of waves about 100,000 times shorter than those of light, Ruska posited that if electrons could be focused on an object the same way …
