As we learned

Property of EM wave -

It carries energy as it propagates. The higher the frequency, the higher the energy associated with the wave. 

 E=\frac{hc}{\lambda }\rightarrow \text{Energy of EM wave during propagation}

\lambda =\frac{hc}{E}

\lambda =\frac{6.6\times 10^{-34}\times 3\times 10^{8}}{14.4\times 10^{3}\times 1.6\times 10^{-19}}=0.8A\rightarrow \text{X-Ray Region}
