When the voltage applied to and X-ray tube is increases from V_(1)=10KV "to" V_(2)=20kV, the wavelength difference between the K_(alpha) line and short wavelengthlimit of the continuous X-ray spectrum increases by a factor 3. The atomic number of the element of which the tube anticathode is made will be |
