Worksheet: X-Ray Diffraction
In this worksheet, we will practice calculating the angles of diffraction maxima and minima for diffraction using X-rays.
X-rays are produced by striking a target with a beam of electrons. Prior to striking the target, the electrons are accelerated by an electric field, increasing their potential energy by , where is the charge of an electron and is the voltage of the electric field. If , what is the minimum wavelength of the emitted radiation?
On a certain crystal, a second-order X-ray diffraction maximum is observed at an angle of relative to its surface, using an X-ray source of unknown wavelength. Additionally, when illuminated with a known wavelength of 0.106 nm, a second-order maximum is detected at .
Find the spacing between the reflecting planes.
Find the unknown wavelength.
