Question

Find the de-Broglie wavelength associated with an electron accelerated under a potential difference of V volts.

Answer 1

De Broglie Wavelength associated with Accelerated Electrons The de Broglie wavelength associated with electrons of momentum p is given by

see the 1st box

where m is mass and v is velocity of electron. If Ek is the kinetic energy of electron, then

see the 2nd box

If V volt is accelerating potential of electron, then Kinetic energy,

see the last box

This is the required expression for de Broglie wavelength associated with electron accelerated to potential of V volt.
