Vedclass · Answer

(B) The continuous spectrum of $X-$rays is produced due to the deceleration of electrons as they strike the target material (Bremsstrahlung radiation). Since the kinetic energy of an electron is $K = eV$, where $V$ is the accelerating voltage, the maximum energy of a photon emitted is equal to the kinetic energy of the electron. Thus, $h 
u_{max} = eV$, which implies $hc / \lambda_{min} = eV$. Therefore, $\lambda_{min} = hc / eV$. This shows that there is a definite short wavelength limit (minimum wavelength) for a given accelerating voltage, while all wavelengths greater than this are present in the spectrum.
