The ratio of the \[{{\lambda }_{\min }}\]in a Coolidge tube to \[{{\lambda }_{deBroglie}}\] of the electrons striking the target depends on accelerating potential V as

\[\frac{{{\lambda }_{\min }}}{{{\lambda }_{deBroglie}}}\propto \frac{1}{V}\]

\[\frac{{{\lambda }_{\min }}}{{{\lambda }_{deBroglie}}}\propto \sqrt{V}\]

\[\frac{{{\lambda }_{\min }}}{{{\lambda }_{deBroglie}}}\propto V\]

\[\frac{{{\lambda }_{\min }}}{{{\lambda }_{deBroglie}}}\propto \frac{1}{\sqrt{V}}\]
