Here, \mathrm{\lambda=\frac{h c}{\Delta E}}
Since energy difference of \mathrm{ k_\alpha} is less than \mathrm{ k_\beta}

\begin{aligned} \mathrm{\Delta E_{K_\alpha}} &\mathrm{<\Delta E_{K_\beta}} \\ \Rightarrow \quad\mathrm{ \lambda_{k_\beta} }&\mathrm{ <\lambda_{k \alpha} }\end{aligned}
Therefore 1 is \mathrm{k_\beta} and 2 is \mathrm{k_\alpha}
