Vedclass · Answer

(C) In an $X-$ray tube,electrons are accelerated by a potential difference $V$ and strike a metal target. This process produces a continuous spectrum of $X-$rays due to Bremsstrahlung (braking radiation). As an electron decelerates,it emits a photon with energy $E = hf = hc/\lambda$. The maximum energy of the emitted photon corresponds to the kinetic energy of the incident electron,$E_{max} = eV = hc/\lambda_{min}$. Therefore,the emitted $X-$ray spectrum contains all wavelengths greater than or equal to this minimum wavelength $\lambda_{min} = hc/eV$. Thus,the beam consists of all wavelengths larger than a certain minimum wavelength.
