electron microscope 3d

It is a sophisticated form of microscope, which can provide a higher magnification of the object (up to 1,00,000 times or more). The electron microscope employs an electron beam emanating from a cathode, instead of light as in the compound microscope..

In optical microscope, the ray of light can be bent by a lens system. By placing the object and the lens system in such a way, we control the direction of the ray to get a magnified image of the object. Since as 'electron' carriers charge it is possible to change the direction o..

It is used for the study of three-dimensional surface view of a given specimen. Its resolving power is also around 2 to 10 0 A. fig. 3.5 - Scanning Electron Microscope..

Upto the year 1924, electron was exclusively regarded as a particle. However, in 1924, de-Broglie suggested that an electron behaves both as a material particle and as a wave. Just like light, some experimental facts can be explained by assuming electrons as tiny part..

In these atoms the energy of orbitals have the same values of 'n' but different values of 'l'. Thus both values of 'n' and 'l' determine the energy of an orbital. The following hold good for multi-electron atoms. Different orbitals having the same principle quantum number 'n' (sub shel..
