Changing the accelerating voltage of an x-ray machine without changing the target material must change:
A)the work function of the material.
B)the wavelength of all the x-rays produced.
C)the wavelength of the minimum wavelength x-ray that will be produced.
D)Both b and c are correct.

Question

Quizplus · Accepted Answer

Changing the accelerating voltage affects the energy of the electrons striking the target, which in turn changes the minimum wavelength of the x-rays produced according to the equation λ_min = hc/eV, where V is the accelerating voltage.
