Question

What is the maximum frequency produced by 30kv electrons?

Answer 1

Potential of the electrons, V=30kv=3×104V

Hence, energy of the electrons, E=3×104eV

Maximum frequency produced by the X-rays = v

The energy of the electrons is given by the relation :

e=hv where, h= planck's constant =6.626×10−34Js

so, v=E/h

=(1.6×10−19×3×104)/6.626×10−34

=7.24×1018Hz
