As we learned

 

De - Broglie wave -

A moving material particle can be associated with wave

- wherein

Wave associaated with the moving material particle .

 

 \lambda =\frac{hc}{E}=\frac{6.6\times 10^{-34}\times 3\times 10^{8}}{1\times 1.6\times 10^{-19}}\times 10^{10}A^{\circ}

=12.375\times 10^{3}A^{\circ}
