Calculating the Kinetic Energy of an Electron in X-Ray Radiation

In summary, kinetic energy is the energy an object possesses due to its motion. It can be calculated using the formula KE = 1/2 * m * v^2, where m is the mass of the object and v is its velocity. X-ray radiation is a type of electromagnetic radiation with high energy and short wavelengths, commonly used in medical imaging and industrial processes. The kinetic energy of an electron in X-ray radiation can be calculated using the equation KE = h * f - W, where h is Planck's constant, f is the frequency of the radiation, and W is the work function of the material the electron is in. The kinetic energy of an electron in X-ray radiation can be affected by the frequency and intensity of the

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

If there is nothing else mentioned, I too think that KE = hc/λ.
