In an electron microscope, the electrons are accelerated by a voltage of 14kV. If the voltage is changed to 224 kV, then the de Broglie wavelength associated with the electrons would

An electron microscope uses electrons accelerated by a voltage of 50 kV. Determine the de Broglie wavelength associated with the electrons. If other factors ( such as numerical aperture, etc. ) are taken roughly to be the same, how does the resolving power of an electron microscope compare with that of an optical microscope which uses yellow light ( lambda_(y) = 5.9 xx 10^(-7) m ) .

If the potential difference used to accelerate electrons is doubled, by what factor does the de-Broglie wavelength associated with the electrons change ?

An electron and an alpha particle have same kinetic energy. How are the de Broglie wavelengths associated with them related ?
