Textbook Problem

The kinetic energy of an electron accelerated in an x-ray tube is 100 keV. Assuming it is nonrelativistic, what is its wavelength?

To determine

The wavelength of an electron, if the kinetic energy of an electron accelerated in an x-ray tube is 100keV.

Explanation

Given info:

Kinetic energy of electron is K=100keV

Formula used:

Using De Broglie formula,

  λelectron=hvmelectroneq.(1)

Kinetic energy of electron is

  K=melectronv22eq.(2)

Calculation:

Solving for speed of electron from eq
