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

Text Solution

Verified by Experts

de Broglie wavelength,
`lambda = ( h )/( sqrt( 2mqV)) prop ( 1)/( sqrt(V))`
If potential difference V is doubled, the de Broglie wavelength is decrased to `(1)/( sqrt(2))` time.

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 ) .
