Electrons used in an electron microscope are accelerated by a voltage 25 kv. If the voltages increased to 100 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 ?
