A) \[\frac{{{\lambda }_{\min }}}{{{\lambda }_{deBroglie}}}\propto \sqrt{V}\]
B) \[\frac{{{\lambda }_{\min }}}{{{\lambda }_{deBroglie}}}\propto V\]
C) \[\frac{{{\lambda }_{\min }}}{{{\lambda }_{deBroglie}}}\propto \frac{1}{\sqrt{V}}\]
D) \[\frac{{{\lambda }_{\min }}}{{{\lambda }_{deBroglie}}}\propto \frac{1}{V}\]
Correct Answer: C
Solution :
[c] \[{{\lambda }_{\min }}=\frac{hc}{eV}\] and \[{{\lambda }_{de-broglie}}=\frac{h}{p}=\frac{h}{\sqrt{2meV}}.\]
