Homework Statement
The minimum wavelength observed in x-ray radiation is 1.23 angstroms. (1 angstrom = 10E-10m). What is the KE, in eV, of the primary electron hitting the target?
Homework Equations
eV = hc/λ
and since all the potential energy becomes kinetic...
is the answer simply
KE = hc/λ?
hc = 1240 nm*ev and λ=12.3nm
