When sodium is bombarded with electrons accelerated through a potential difference $\mathrm{\Delta }V$, its x-ray spectrum contains emission peaks at 1.04 keV and 1.07 keV. Find the minimum value of $\mathrm{\Delta }V$ required to produce both of these peaks.

The equation for the energy required to produce the peaks is given by,
$E=e\mathrm{\Delta }V$
Here, E is the energy peak, e is the charge of the electron and AV is the potential difference required.
Rewriting the above equation,
$\mathrm{\Delta }V=\frac{E}{e}$
Substitute the numerical value in the equation to find the value of $\mathrm{\Delta }V$ corresponding to 1.04keV.
