Electrons Are Used to Produce X-Rays by Allowing a Beam

question 41

Multiple Choice

Electrons are used to produce X-rays by allowing a beam of electrons to strike a heavy metal surface.What is true about the wavelengths of the characteristic X-rays that are produced in such a situation?

• A) There is a continuous range of wavelengths produced,up to a maximum that depends on the energy of the electron beam used.
• B) There is a single wavelength of X-ray produced that depends on the energy of the electron beam used.
• C) There are a few specific wavelengths that are produced for a given metal and their wavelength is independent of the energy of the electron beam used.
• D) There is a continuous range of wavelengths produced,down to a minimum that depends on the energy of the electron beam used.
