In an electron microscope, the resolution that can be achieved is of the order of the wavelength of electrons used. To resolve a width of `7.5 xx 10^(-12)` m, the minimum electron energy required is close to :

In an electron microscope, the resolution that can be achieved is of the order of the wavelength of electrons used. To resolve a width of 17.5 xx 10^(-12) m, the minimum electron energy required is close to:

The wavelength of an electron of energy 10keV will be

The wavelength of an electron of energy 10 keV will be :

The minimum energy required to remove an electron is called

The minimum energy required to remove an electron is called

We wish to see inside an atom. Assuming the atom to have a diameter 10 pm, this means that one must be able to resolve a width of say 10 pm. If electron microscope is used, the minimum electron energy required is about

We wish to see inside an atom. Assuming the atom to have a diameter of 100 pm, this means that one must be able to resolve a width of say 10 pm. If an electron microscope is used, the minimum electron energy required is about
