In a coolidge tube, the potential difference used to accelerate the electrons is increased from 12.4 kV to 24.8 kV. As a result, the difference between the wavelength of ${\mathrm{K}}_{\alpha }$-line and minimum wavelength increases two-fold. The wavelength of the ${\mathrm{K}}_{\alpha }$ line is $\left(\frac{hc}{e}=12.4\mathrm{kV}\mathring{A}\right)(\mathrm{A})1\mathring{A}$
