If the cutoff wavelength for a particular material is 510nm considering the photoelectric effect, what will be the maximum amount of kinetic energy obtained by a liberated electron when light with a wavelength of 402nm is used on the material? Answer in eV
The electron beam in a scanning electron microscope (SEM) can have an energy ranging from 0.2 keV to 40 keV.
(Note: an eV is an electronvolt, the measure of an amount of kinetic energy for a single electron.
1 eV = 1.60218×10−19 J and 1 J = 1 kg m2 s−2).
What is the de Broglie wavelength of the electron beam in the SEM when the electrons are accelerated to kinetic energy of 6.6 keV?
