Electrons are used to produce x-rays by allowing a beam of electrons to strike a heavy metal surface. When the speed of the electrons in the beam is increased, this produces
A) x-rays with higher energies
B) x-rays with longer wavelengths
C) faster x-rays
D) more x-rays per unit time

Question

Quizplus · Accepted Answer

The speed of the electrons in the beam is directly related to the energy of the resulting x-rays. As the speed increases, so does the energy of the x-rays produced, leading to higher energy x-rays.
