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 bremsstrahlung X-rays that are produced in such a situation?
A. 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. B. There is a single wavelength of X-ray produced that depends on the energy of the electron beam used. C. There is a continuous range of wavelengths produced, down to a minimum that depends on the energy of the electron beam used. D. There is a continuous range of wavelengths produced, up to a maximum that depends on the energy of the electron beam used.
