A)double.
B)quadruple.
C)decrease to one-half of their original energy.
D)remain constant.
E)None of these is correct.

Question

Quizplus · Accepted Answer

The wavelengths of the characteristic lines are determined by the energy levels of the electrons in the atoms of the anode material. These energy levels are fixed properties of the atoms and do not change when the voltage across the X-ray tube is altered.
