Description

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.
