Magnetic Particle Testing

Résumé du livre

In the generation of X-rays with an X-ray tube, the minimum wavelength?min that is produced is given by?min=hc/eV where h=Planck's constant,6.62611034Js, c=speed of light,2.9979108m/s, e=elementary charge,1.60221019C, and V=the tube voltage. Therefore,?min=1240/Vnm The wavelength of maximum X-ray emission?peak is approximately 3/2 times the minimum wavelength. That is,?peak?1860/Vnm Table 3.1 lists?min and?peak as functions of V.
